摘要：

Different "functionalized" alkyl 3-oxo-butyrates (2) were reacted with 5-amino-3-Q-1 H-1,2,4-triazoles (1) to yield 3 and 4 type 1,2,4-triazolo[1,5-a]pyrimidinones. In case of 2 (R1=methyl, R2=1-ethoxycarbonylethyl, R3=ethyl) beside the corresponding derivative 4 the unexpected 5,6-dihydro-6,8-dimethyl-7-ethoxycarbonyl-3-methylthio-1,2,4-triazolo[4,3-a]-1,3-diazepin-5(9 H)-one (7) was isolated, representing a novel ring system. © 1990 Springer-Verlag.
