Synthesis of some novel annelated 1,2,3-selena/thiadiazoles and 2H-diazaphospholes

摘要

A number of annelated heterocyclic indene derivatives having 1,2,3-selena/thiadiazole and 2H-1,2,3diazaphosphole rings have been synthesized by exploiting the alpha-ketomethylene functionality in some novel 1-methyl-piperidin-4-ones and 1-oxo-tetrahydrothiopyran-4-ones and were characterized by their physical and spectral data.
