The first synthesis of 1-methyl-15-hydroxy-20-deethyldasycarpidone has been achieved via acid-induced cyclization of the 4-hydroxy-4-indolylcarbonyl-2-piperidinecarbonitrile which in turn are obtained by a modified Polonovski reaction. The formation of lactams 6 and 7 in the acid cyclization conditions are reported for the first time.
通过酸诱导的4-羟基-4-吲哚基羰基-2-哌啶腈的环化反应,可以实现1-甲基-15-羟基-20-去乙基大黄酮的首次合成,而环化反应又是通过修饰的Polonovski反应获得的。首次报道了在酸环化条件下内酰胺6和7的形成。
