A Convenient Synthesis of 2H-3,4-Dihydro-1,4-Benzothiazines
摘要:
Aminothioalkenols react with paratoluenesulfonic acid in benzene or with phosphoric acid in toluene, and provide mainly heterocyclization in 2H-3,4-dihydro-1,4- benzothiazines; formation of some indenes and diene (in one case) was observed too.
