摘要：
Cyclization of aryl-, aroyl-, and (4,6-dimethylpyrimidin-2-yl)cyanamides with methyl anthranilates, 2-aminophenyl ketones, and methyl 2-(3-oxopiperazin-2-yl)acetate leads to 2-amino-3,4-dihydroquinazolin-4-one, 2-aminoquinazoline, and 6-amino-1,3,4,8,9,9a-hexahydro-2H-pyrazino[1,2-c]pyrimidine-1,8-dione derivatives, respectively.
