Regioselective synthesis of 1,4 oxathiane derivatives via multicomponent reaction
A simple and efficient reaction between malononitrile, elemental sulfur, and three membered heterocyclic compounds is reported. This route turned out to be an useful and straightforward method for the regioselective and atom economical synthesis of 1,4 oxathiane and 1,4 thiazine derivatives.Graphical abstract
