An efficient halogen-free Cs2CO3-promoted methylene insertion into disulfide bonds has been achieved using acetone as a methylene source under mild conditions. This method provides a convenient and practical route to dithioacetals in up to 96% yield with good functional group compatibility.
A one-pot stereoselective synthesis of electron-deficient 4-substituted (E, E)-1-arylsulfonylbuta-1,3-dienes and their chemoselective [3+2] cycloaddition with azomethine ylides - A simple synthesis of 1,3,4-trisubstituted pyrrolidines and pyrroles

A simple and efficient method for the synthesis of (E,E)-1-(arylsulfonyl) buta-1,3-dienes bearing electron-withdrawing substituents like cyano and ethoxycarbonyl at position 4, involving a one-pot alkylation of bis(phenylsulfonyl)methane with trans-ethyl 4-bromocrotonate/trans-4- bromocrotononitrile, and elimination of arylsulfinic acid, is described. These dienes undergo facile mono [3+2] cycloaddition with azomethine ylides chemoselectivity to furnish functionalized 1,3,4-trisubstituted pyrrolidines. Oxidation of these cycloadduct with MnO2·SiO2 under mild conditions provides 1,3,4-trisubstituted pyrroles. Georg Thieme Verlag Stuttgart. New York.
