Abstract

Reactions of ethyl 3‐aryl‐2‐benzoylpropenoates 1 with guanidine and N‐alkyl(or benzyl)guanidines have been investigated. Ethyl 2‐aminodihydro‐5‐pyrimidinecarboxylate derivatives 3, 4 or 5, and 3,7‐diethoxy‐carbonyl‐4,6‐dihydro‐2,4,6,8‐tetraaryl‐1__H__‐pyrimido[1,2‐a]pyrimidines 6 have been synthesized.
