The lithium salts of t-butyl-and trityl-hydrazones react with methyl crotonate to form C-trapped azo-esters and similar products were observed from a thermal ene-reaction of aldehyde t-butylhydrazones with methyl acrylate or acrylonitrile, and aldehyde phenylhydrazones with methyl acrylate; these products can be diverted into synthetically useful γ-keto-esters, γ-keto-nitriles, saturated esters, γ
叔丁基hydr和三苯甲基-的
锂盐与
巴豆酸甲酯反应形成C捕获的偶氮酯,并且通过醛叔丁基hydr与
丙烯酸甲酯或
丙烯腈的热烯反应,以及醛苯hydr与
丙烯的热烯反应观察到类似的产物。
丙烯酸甲酯 这些产品可以分为合成有用的γ-
酮酯,γ-酮腈,饱和酯,γ-烷基-
2-吡咯烷酮和γ-
氨基酯。
