Synthesis and Recylization of 2,3,9,10-Tetrahydro-8H-[1,4]Dioxino[2,3-f]-[1,3]Thiazino[3,2-a]Benzimidazolium Salts
摘要:
A series of [1,3]thiazino[3,2-a]benzimidazolium salts modified in the benzene ring by a condensed 1,4-dioxane ring has been prepared. Reaction with epichlorohydrin occurs with recyclization to form derivatives of 3-(2,3-epithiopropyl)benzimidazol-2-one.
