A new and facile tetrachlorosilane-promoted one-pot condensation for the synthesis of a novel series of tetracyclic 1,5-thiazepines
摘要:
A new and facile approach for the one-pot synthesis of a novel series of tetracyclic 1,5-thiazepines is described. The reaction occurs through cyclocondensation of fused cyclic ketones, aromatic aldehydes, and 2-aminothiophenol using tetrachlorosilane as a promoter in methylene chloride at ambient temperature.
