本文报道NBS与β-甲基-γ-羰基-α,β-不饱和酸酯类化合物的反应。实验表明在这类化台物中,双键异构体上烯丙位的溴化反应与一般的完全不同,酯基和羰基的同时存在可大大活化亚甲基上氢对反应的活性。
This article reports the reaction of NBS with β-methyl-γ-carbonyl-α, β-unsaturated acid esters. Experiments show that in this class of compounds, double bond isomers of the allylic bromination reaction with the general completely different ester and carbonyl co-exist can greatly activate the hydrogen on the reaction of methylene.
