Synthesis of 1-Iminoisothiochroman Derivatives Based on Reactions of 2-Lithio-β-methoxystyrene Derivatives with Isothiocyanates Followed by Acid-Mediated Cyclization
摘要:
The reaction of 2-lithio-beta-methoxystyrene derivatives with isothiocyanates yields the corresponding 2-(2-methoxyvinyl)thiobenzamide derivatives. Treatment of these thiobenzamides with concentrated hydriodic acid affords 1-imino-3-methoxyisothiochroman (1-imino-3-methoxy-3,4-dihydro-1H-2-benzothiopyran) derivatives.
