Synthesis of 7-oxo-dihydrospiro[indazole-5,4?-piperidine] acetyl-CoA carboxylase inhibitors

Synthesis of oxo-dihydrospiroindazole-based acetyl-CoA carboxylase (ACC) inhibitors is reported. The dihydrospiroindazoles were assembled in a regioselective manner in six steps from substituted hydrazines and protected 4-formylpiperidine. Enhanced regioselectivity in the condensation between a keto enamine and substituted hydrazines was observed when using toluene as the solvent, leading to selective formation of 1-substituted spiroindazoles. The 2-substituted spiroindazoles were formed selectively from alkyl hydrazones by ring closure with Vilsmeier reagent. The key step in the elaboration to the final products is the conversion of an intermediate olefin to the desired ketone through elimination of HBr from an O-methyl bromohydrin. This methodology enabled the synthesis of each desired regioisomer on 50-75 g scale with minimal purification. Acylation of the resultant spirocyclic amines provided potent ACC inhibitors.

Oxalic Diamides and tert-Butoxide: Two Types of Ligands Enabling Practical Access to Alkyl Aryl Ethers via Cu-Catalyzed Coupling Reaction

A robust and practical protocol for preparing alkyl aryl ethers has been developed, which relies on using two types of ligands to promote Cu-catalyzed alkoxylation of (hetero)aryl halides. The reaction scope is very general for a variety of coupling partners, particularly for challenging secondary alcohols and (hetero)aryl chlorides. In case of coupling with aryl chlorides and bromides, two oxalic diamides serve as the powerful ligands. The tert-butoxide is first demonstrated as a ligand for Cu-catalyzed coupling reaction, leading to alkoxylation of aryl iodides complete at room temperature. Additionally, a number of carbohydrate derivatives are applicable for this coupling reaction, affording the corresponding carbohydrate-aryl ethers in 29-98% yields.

Concise synthesis of highly substituted benzo[a]quinolizines by a multicomponent reaction/allylation/heck reaction sequence

The combination of the recently developed multicomponent construction of highly substituted 3,4-dihydropyridones with subsequent allylation and intramolecular Heck-type cyclization allows the straightforward construction of benzo[a]quinolizines, a class of polycyclic compounds that- despite their interesting pharmacological and photochemical properties- have little precedent in the literature. After optimization of the individual steps, we used this reliable three-step sequence to generate a small library of diversely substituted benzo[a]quinolizines and various heterocyclic analogs.

Enantioselective Radical Ring-Opening Cyanation of Oxime Esters by Dual Photoredox and Copper Catalysis

Catalytic enantioselective chemical reactions involving highly reactive radical species remain largely unexplored. We report herein for the first time a novel enantioselective radical ring-opening cyanation of redox-active oxime esters by dual photoreodox and copper catalysis. This mild protocol shows good functional group tolerance and broad substrate scope, producing a wide range of optically active alkyl dinitriles with high yields and excellent enantioselectivities, which are difficult to access traditionally.

Photon-Quantitative 6pi-Electrocyclization of a Diarylbenzo[b]thiophene in Polar Medium

The high reactivity of 6pi-electrocyclization in polar solvents has remained one of the important challenges for diarylethenes because of the emergence of a twisted intramolecular charge transfer (TICT) state at the excited state in such polar media, which usually quenches the photocyclization reaction. Herein we report on the preparation and highly efficient photocyclization of 2,3-diarylbenzo[b]thiophenes with nonsymmetric side-aryl units in a polar solvent. While the dithiazolylbenzo[b]thiophene showed a suppressed quantum yield of 6pi-electrocyclization of 54% in methanol, the replacement of a thiazole unit with a thiophene ring led to a photon-quantitative 6pi-cyclization reaction. The nonsymmetrical modification into the side-aryl units was considered to enhance the CH/pi interactions between side-aryl units to support a photoreactive conformation in methanol. The stabilization of the photochromic reactive conformation is expected to suppress the formation of the TICT state at the excited state, leading to highly efficient photoreactivity.
