Three-component reaction of isocyanide with dialkyl acetylenedicarboxylate and alkyl mercaptan: Preparation of new derivatives of stable ketenimines

Three-component synthesis of stable ketenimines containing a sulfur group based on a capture profile of a zwitterionic intermediate is described. Thus, the reactions of zwitterions, generated from isocyanide and dialkyl acetylenedicarboxylate, react with alkyl mercaptans in CH2Cl2 to afford ketenimines in good yields.

Direct benzothiophene formation via oxygen-triggered intermolecular cyclization of thiophenols and alkynes assisted by manganese/PhCOOH

An intermolecular oxidative cyclization between thiophenols and alkynes for benzothiophene formation has been established. A variety of multifunctional benzothiophenes are synthesized. In addition, we demonstrated that the obtained benzothiophenes can be

Generation of Nonstabilized Thiazolium and 2-Methylthiazolium Methylides

Desilylation of 3-(trimethylsilylmethyl)thiazolium triflates including 2-methyl derivatives with CsF generates the corresponding thiazolium methylides which are trapped with acetylenic and olefinic dipolarophiles.This paper presents the first example for the generation of nonstabilized thiazolium methylides including 2-methyl derivatives.

Reactions of Benzenesulphenyl Chloride with α,β-Unsaturated Compounds: Part III - Reactions with Maleic Anhydride

The interaction of maleic anhydride (2) and benzenesulphenyl chloride (1) in the presence of pyridine gives 1,2-bis(phenylthio)maleic anhydride (3) as the sole product.Monophenylthiomaleic anhydride (4) on the other hand, is the only product of the reaction between 2 and 1 in the presence of triphenylphosphine (13).Some aspects of the mechanism of these two reactions have been discussed.

Reaction of Benzenesulphenyl Chloride with α, β-Unsaturated Compounds: Part I - Reactions with Methyl Crotonate and Methyl Cinnamate in Presence of Pyridine

Reaction of benzenesulphenyl chloride (PhSCl) with α, β-unsaturated systems, in the presence of pyridine, offers a convenient route to sulphenylate regiospecifically the α-position of such systems.The specific role of pyridine and the product analysis have been examined and rationalised on the basis of the formation of pyridine-assisted carbanion intermediates and the structure/stability of these carbanions.
