摘要

Abstract Site-selectivity of dipolar cycloaddition to the title compound was studied. Azomethine X afforded a 1: 1 cycloadduct XI at the deactivated double bond at room temperature; upon thermolysis at 110 C it afforded the acetylated enamine XIII which was formed via a direct cycloaddition at the mentioned temperature. The cycloaddition course was investigated in various solvents; the enamine XIV formed by solvolysis of XIII was the ...
