Synthesis of 1-iminoisothiochroman derivatives based on reactions of 2-lithio-b-methoxystyrene derivatives with isothiocyanates followed by acid-mediated cyclization.
[摘要]：The reaction of 2-lithio-b-methoxystyrenes with isothiocyanates yields the corresponding 2-(2-methoxyvinyl)thiobenzamides. Treatment of these thiobenzamides with concd. HI affords 1-imino-3-methoxyisothiochromans (1-imino-3-methoxy-3,4-dihydro-1H-2-benzothiopyrans).
