摘要

Abstract A mild, simple and efficient procedure for the preparation of 3, 4-dihydropyrimidin-2 (1H)-ones and-thiones is described using N-sulfonic acid poly (4-vinylpyridinium) chloride (NSPVPC) as a heterogeneous and efficient catalyst under solvent-free conditions. Simple methodologies, easy work-up procedure, easy preparation of the catalyst, excellent yields and very short reaction times are among the other advantages of this work. Further, the ...
