Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 3395-91-3, is researched, Molecular C4H7BrO2, about Catalytic Asymmetric Homologation of Ketones with α-Alkyl α-Diazo Esters, the main research direction is keto esters chemoselective regioselective enantioselective preparation; alkyl diazoester ketone scandium catalyst homologation chemoselective regioselective enantioselective.Name: Methyl 3-bromopropanoate.

The homologation of ketones with diazo compounds was a useful strategy to synthesize one-carbon chain-extended acyclic such as PhC(O)CMeCO2MeR [R = allyl, Bn, CH2(2-naphthyl), etc.] or ring-expanded cyclic ketones e.g., I. However, the asym. homologation of acyclic ketones with α-diazo esters remains a challenge due to the lower reactivity and complicated selectivity. Herein, the enantioselective catalytic homologation of acetophenone and related derivatives with α-alkyl α-diazo esters was reported utilizing a chiral scandium(III) N,N’-dioxide as the Lewis acid catalyst. This reaction supplies a highly chemo-, regio-, and enantioselective pathway for the synthesis of optically active β-keto esters with an all-carbon quaternary center through highly selective alkyl-group migration of the ketones. Moreover, the ring expansion of cyclic ketones was accomplished under slightly modified conditions, affording a series of enantioenriched cyclic β-keto esters. D. functional theory calculations was carried out to elucidate the reaction pathway and possible working models that could explain the observed regio- and enantioselectivity.

There is still a lot of research devoted to this compound(SMILES：O=C(OC)CCBr)Name: Methyl 3-bromopropanoate, and with the development of science, more effects of this compound(3395-91-3) can be discovered.

Safety of Methyl 3-bromopropanoate. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Design, Synthesis, and Activity Evaluation of Novel Acyclic Nucleosides as Potential Anticancer Agents In Vitro and In Vivo. Author is Hao, Er-Jun; Li, Gong-Xin; Liang, Yu-Ru; Xie, Ming-Sheng; Wang, Dong-Chao; Jiang, Xiao-Han; Cheng, Jia-Yi; Shi, Zhi-Xian; Wang, Yang; Guo, Hai-Ming.

In the present work, 103 novel acyclic nucleosides were designed, synthesized, and evaluated for their anticancer activities in vitro and in vivo. The structure-activity relationship (SAR) studies revealed that most target compounds inhibited the growth of colon cancer cells in vitro, of which (chloro-9H-purinyl)dodecanol I exhibited the most potent effect against the HCT-116 and SW480 cells with IC50 values of 0.89 and 1.15μM, resp. Furthermore, all of the (R)-configured acyclic nucleoside derivatives displayed more potent anticancer activity compared to their (S)-counterparts. Mechanistic studies revealed that compound I triggered apoptosis in the cancer cell lines via depolarization of the mitochondrial membrane and effectively inhibited colony formation. Importantly, I inhibited the growth of the SW480 xenograft in a mouse model with low systemic toxicity. These results indicated that acyclic nucleoside compounds are viable as potent and effective anticancer agents, and I may serve as a promising lead compound that merits further attention in future anticancer drug discovery.

Through the article, more information about this compound (cas:3395-91-3) is conveyed.

Sulfonimidamides present exciting opportunities as chiral isosteres of sulfonamides, with potential for addnl. directional interactions. Here the authors present the first modular enantioselective synthesis of sulfonimidamides, including the first stereoselective synthesis of enantioenriched sulfonimidoyl fluorides, and studies on their reactivity. A new route to sulfonimidoyl fluorides is presented from solid bench-stable, N-Boc-sulfinamide salt building blocks. Enantioenriched arylsulfonimidoyl fluorides are shown to be readily racemized by fluoride ions. Conditions are developed, which trap fluoride and enable the stereospecific reaction of sulfonimidoyl fluorides with primary and secondary amines (100% es) generating sulfonimidamides with up to 99% ee. Aryl and alkyl sulfonimidoyl fluoride reagents are suitable for mild late stage functionalization reactions, exemplified by coupling with a selection of complex amines in marketed drugs.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Catalytic Hydrogenation of Cyclic Carbonates: A Practical Approach from CO2 and Epoxides to Methanol and Diols, published in 2012, which mentions a compound: 1086138-36-4, Name is Bis(2-(Di(adamantan-1-yl)phosphino)ethyl)amine, Molecular C44H69NP2, Formula: C44H69NP2.

A highly efficient catalytic hydrogenation of cyclic carbonates was developed for the preparation of methanol with the cogeneration of the corresponding diols by using (PNP) Ru”” pincer complexes as the catalysts under relatively mild conditions. This process has provided a facile approach for the simultaneous production of two important bulk chems., methanol and EG, from ethylene carbonate, which is industrially available by reacting ethylene oxide with CO2. The coupling of the present catalytic system with the process of ethylene carbonate production in the omega process is expected to establish a new bridge from CO2 and ethylene oxide to methanol and EG. Apart from the clean production of diol, a big bonus of the present protocol is the efficient chem. utilization of CO2, which represents a distinct advantage in terms of sustainability over the omega process, which gives back CO2. Moreover, this catalytic system has also provided a potential process for the utilization of waste poly(propylene carbonate) as a resource to afford 1,2-propylene diol and methanol through hydrogenative depolymerization, and a convenient method for the preparation of deuterated methanol from CO2 and D2. A possible catalytic mechanism is proposed, in which the NH moiety of the ligand is demonstrated to be critically important in facilitating the reduction of the carbonate C=O bond through secondary coordination sphere interactions with substrates.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Methyl 3-bromopropanoate, is researched, Molecular C4H7BrO2, CAS is 3395-91-3, about Design, synthesis and biological evaluation of dihydro-2-quinolone platinum(IV) hybrids as antitumor agents displaying mitochondria injury and DNA damage mechanism, the main research direction is platinum quinoloneoxoalkylcarboxylate complex preparation antitumor DNA cleavage.Application In Synthesis of Methyl 3-bromopropanoate.

The design of novel platinum(IV) complexes with mitochondria injury competence, besides the DNA damage mechanism, is a promising way to develop new platinum drugs. Herein, dihydro-2-quinolone (DHQLO) as a mitocan was incorporated into the platinum(IV) system for the first time to prepare a new series of DHQLO platinum(IV) compounds Complex 1b could effectively inhibit the proliferation of tumor cells in vitro and in vivo. It accumulated at higher levels in both whole cells and DNA, and easily underwent intercellular reduction to release platinum(II) and DHQLO moieties. The released platinum(II) complex caused serious DNA damage by covalent conjunction with the DNA duplex, and remarkably increased the expression of the γ-H2AX protein. Moreover, 1b also caused serious mitochondria injury to induce mitochondrial membrane depolarization and increase ROS generation. Such actions upon DNA and mitochondria activate the p53 apoptotic pathway synergetically in tumor cells by upregulating the protein p53 and apoptotic proteins caspase9 and caspase3, which efficiently promoted the apoptotic death of tumor cells. Compound 1b with such synergic mechanism exhibited great potential in reversing cisplatin resistance and improving antitumor efficacies.
