A methodology for the formal addition of β-acylalkenyl anions was developed under Brønsted base catalysis. The two-step reaction, which involves the catalytic addition of α-oxygenated propargyl anions generated via [1,2]-phospha-Brook rearrangement to electron-deficient ketones and subsequent alcoholysis, afforded tertiary alcohols having an enone moiety.
在布朗斯台德碱催化下开发了一种正式加成 β-酰基烯基阴离子的方法。该两步反应涉及通过[1,2]-磷酸-布鲁克重排生成的α-氧化炔丙基阴离子催化加成为缺电子酮以及随后的醇解,得到具有烯酮部分的叔醇。
