Reaction of 2-alkylthio-substituted 2-penten-4-ynals with <i>N</i>,<i>N</i>- and <i>N</i>,<i>O</i>-binucleophiles

Abstract

The condensation of 2-alkylthiosubstituted 2-en-4-ynals with N , N - and N , O -binucleophiles gives the corresponding 1,3-perhydrodiazines, 1,3-imidazolidines, and 1,3-oxazolidines with an original combination of substituents.
