NaHSO3-Mediated Direct Synthesis of Sulfinic Esters from Sulfonyl Hydrazides under Transition-Metal-Free Conditions

We have developed a protocol for the NaHSO3-promoted esterification of sulfonyl hydrazides with alcohols for the synthesis of sulfinic esters. Various sulfonyl hydrazides could be converted to the corresponding sulfinic esters in good to high yields. The merits of this protocol include mild transition-metal-free reaction conditions, an inexpensive and available reagent, and operational simplicity. Controlled experiments reveal that this transformation probably undergoes via a radical pathway. (Figure presented.).

Metal- And oxidant-free electrochemical synthesis of sulfinic esters from thiols and alcohols

An efficient and eco-friendly electrochemical synthesis of various sulfinic esters from thiols and alcohols via sequential S-H/S bond cleavage and double S-O bond formation under mild reaction conditions has been developed. Stoichiometric oxidants, metal catalysts, activating agents and even added bases were avoided in this method, and the only by-product generated from this reaction was dihydrogen gas which could serve as a green source of energy. Various functional groups are compatible with this green protocol which can be easily conducted on a gram-scale.

ORGANOSULPHUR COMPOUNDS-LXIX OPTICALLY ACTIVE SULPHINATES: A NEW TYPE OF ENANTIOSELECTIVE ASYMMETRIC SYNTHESIS AND KINETIC RESOLUTION

Optically active sulphinates with the sulphur atom as a sole centre of chirality are prepared by two methods.The first involves the reaction of symmetrical sulphites with tert-butylmagnesium chloride in the presence of optically active aminoalcohols.This new asymmetric, enantioselective synthesis affords t-butylsulphinates with 40-70percent enantiomeric excess values.The second approach is based on a new type of kinetic resolution taking place when racemic sulphinates are reacted with tert-butylmagnesium chloride complexed by optically active alkaloid bases.Both the recovered sulphinates and sulphoxides formed in this reaction show moderate optical purities.
