A simple synthesis of several methyl 2-oxo-2,3-dihydrobenzo[b]oxepine-4-carboxylates from Baylis-Hillman adducts of O-benzyl protected 2-hydroxybenzadehydes has been described through the acetylation, cyanation, debenzylation, as well as acid assisted Pinner cyclization.
已经描述了通过乙酰化,氰化,脱苄基以及O-苄基保护的2-羟基苯甲醛的Baylis-Hillman加合物简单合成几种2-oxo-2,3-dihydrobenzo [ b ] oxepine-4-羧酸甲酯的方法。酸辅助的Pinner环化。
