Abstract

We have found a novel and simple approach to synthesis of 2-alkyl-3-(methylthio)-5,6-dihydro-2H-2-thiopyranimines by reactions of isothiocyanates with the carbanion of methylthiobutadiene, generatedin situ when treated with the superbasic system BuLi-t-BuOK. We have established that alkylation of the synthesized thiopyrans with methyliodide in the presence of t-BuOK leads to N-alkyl-1,2-di(methylthio)-2,4-pentadiene-1-imines.
