Synthesis of 6-Alkylidene-5,6-dihydro-4H-1,3-thiazine Derivatives via the Cyclization of N-3-Bromo-3-alkenylthioamides
By the treatment of N-3-bromo-3-alkenylthioamides with sodium hydroxide in DMF-H2O in the presence of tetra-butylammonium bromide, series of 6-alkylidene-5,6-dihydro-4H-1,3-thiazine derivatives were prepared in moderate to good yields. The cyclization is supposed to proceed via both the intramolecular vinylic nucleophilic substitution and the elimination-addition mechanisms (formation of acetylenic intermediates) in a competitive manner.
