The nucleophilic addition of 2-mercaptoethanol to tertiary cyanoalkynyl alcohols takes place regio- and stereospecifically with the formation of 3-hydroxy-2-(2-hydroxyethylthio)-3,3-dialkyl-1-alkene-1-carbonitriles and 2,7-di(1-hydroxy-1-methylethyl)-6-oxa-3-thia-1,7-octadiene-1,8-dicarbonitrile.Under the influence of bases (triethylamine, lithium hydroxide) the former undergo further transformations, giving 2-amino-5,5-dialkyl-4,5-dihydro-4-furanones.
