Synthesis of thiazol, thiazinan, thiadiazin, thiazolidin, triazine, thioxo-pyrimidin and thioxo-imidazolidine by inter-intra molecular cyclization

摘要

Syntheses of five and six membered heterocyclic derivatives by the reaction of disubstituted thiocarbamides with inter-intramolecular cyclizations in catalyst free condition have been reported. The simple product isolation without column, good yields under mild condition, and applicable green matrix are the advantages of present protocol.
