Abstract

The reaction of C₂-substituted 1,2,3,4-tetrahydroquinazolin-4-ones (1) with acetic anhydride and pyridine was carried out in order to elucidate the effect of the C₂-substituent. It was found that the various types of reactions occurred depending on the kind and number of C₂-substituents of 1,2,3,4-tetrahydroquinazolin-4-ones (1).
