Sodium halides as the source of electrophilic halogens in green synthesis of 3-halo- and 3,n-dihalobenzo[b]thiophenes

A convenient methodology for the synthesis of mono- and di-halogenated benzo[b]thiophenes is described herein, which utilizes copper(II) sulfate pentahydrate and various sodium halides in the presence of substituted 2-alkynylthioanisoles. The proposed method is facile, uses ethanol as a green solvent, and results in uniquely substituted benzo[b]thiophene structures with isolated yields up to 96%. The most useful component of this methodology is the selective introduction of bromine atoms at every available position (2?7) around the benzo[b]thiophene ring, while keeping position 3 occupied by a specific halogen atom such as Cl, Br or I. Aromatic halogens are useful reactive handles; therefore, the selective introduction of halogens at specific positions would be valuable in the targeted synthesis of bioactive molecules and complex organic materials via metal-catalyzed cross coupling reactions. This work is a novel approach towards the synthesis of dihalo substituted benzo[b]thiophene core structures, which provides a superior alternative to the current methods discussed herein.

Pd-Catalyzed C-H Annulation of Five-Membered Heteroaryl Halides with Norbornene Derivatives

Complementary to Catellani-type reactions and 1:1 coupling of six-membered halo(hetero)arenes and norbornene (NBE) derivatives, Pd-catalyzed 1:2 coupling of five-membered haloheteroarenes with NBEs was achieved to afford rigid nonplanar heterocycles. Pyrazole, thiophene, furan, and indole underwent exo- and trans-selective annulation. Two strained alkene groups of the resulting products were further manipulated to afford 1-alkylindazoles and ladder polymers. The type of heteroarenes and position of halides along with the choice of ligands and bases were critical to set a preference between C-H annulation and Catellani reactions, which will be useful for the development of Pd-catalyzed, NBE-mediated reactions of heteroarenes.

Study of the Reactivity of Ketone Enolates with 3-Halo-2-amino Derivatives of Benzothiophene under Photostimulated SRN1 Reaction Conditions

Reactivity of the 3-halo-2-amino derivatives of benzothiophene 1a-c and 2 with several ketone enolates 3-5 have been studied under photostimulated SRN1 reaction conditions.The normal substitution product 6 only was obtained in low yields using potassioacetophenone 3 as the enolate ion and 2-(tert-butoxycarbonylamino)-3-chlorobenzothiophene (1a) and 2-(tert-butoxycarbonylamino)-3-iodobenzothiophene (1c) as substrates.In all reactions the main product was the corresponding dehalogenated substrate 7a-b, thus indicating that reduction of the substrate strongly competes with the desired substitution reaction.

Sequential Cross-Coupling/Annulation of ortho-Vinyl Bromobenzenes with Aromatic Bromides for the Synthesis of Polycyclic Aromatic Compounds

A sequential cross-coupling/annulation of ortho-vinyl bromobenzenes with aromatic bromides was realized, providing a direct and modular approach to access polycyclic aromatic compounds. A vinyl-coordinated palladacycle was proposed as the key intermediate for this sequential process. Excellent chemoselectivity and regioselectivity were observed in this transformation. The practicability of this method is highlighted by its broad substrate scope, excellent functional group tolerance, and rich transformations associated with the obtained products.

C2/C4 Regioselective Heteroarylation of Indoles by Tuning C-H Metalation Modes

The development of a rational strategy to achieve the complete regioselectivity and the capability to switch regioselectivity is an appealing, yet challenging, puzzle in transition-metal-catalyzed oxidative Ar-H/Ar-H cross-coupling. Disclosed herein is an iridium-catalyzed C2/C4 regioselective C-H heteroarylation of indoles with the help of a pivaloyl group at the C3 position. The judicious choice of the catalytic systems allows the C2-heteroarylation of indole via a concerted metalation-deprotonation (CMD) process and the C4-heteroarylation via a trimolecular electrophilic substitution (SE3) pathway. The oxidants Cu(OAc)2¡¤H2O and Ag2O are demonstrated to play a vital role in the C2/C4 regioselectivity. In this Article, a heteroaryl-Ir(III)-heteroaryl complex prior to reductive elimination is successfully isolated and characterized, which represents the first example of capturing the bis(hetero)aryl metallic intermediate in oxidative Ar-H/Ar-H cross-coupling. The regiodivergent heteroarylation of indoles developed herein provides an opportunity to rapidly assemble diverse C4- and C2-heteroarylated indoles.

Catalytic Diastereo- and Enantioselective Fluoroamination of Alkenes

The stereoselective synthesis of syn-beta-fluoroaziridine building blocks via chiral aryl iodide-catalyzed fluorination of allylic amines is reported. The method employs HF-pyridine as a nucleophilic fluoride source together with mCPBA as a stoichiometric oxidant, and affords access to arylethylamine derivatives featuring fluorine-containing stereocenters in high diastereo- and enantioselectivity. Catalyst-controlled diastereoselectivity in the fluorination of chiral allylic amines enabled the preparation of highly enantioenriched 1,3-difluoro-2-amines bearing three contiguous stereocenters. The enantioselective catalytic method was applied successfully to other classes of multifunctional alkene substrates to afford anti-beta-fluoropyrrolidines, as well as a variety of 1,2-oxyfluorinated products.
