A new, simple, and short route for the synthesis of simplactones A (1) and B (2) was achieved from a synthetically prepared chiral auxiliary, i.e., the Oppolzer camphor‐derived sultam 4, and (4‐methoxybenzyl)‐protected 3‐hydroxypropanal, in 52 and 48% overall yield, respectively, and with high diastereoselectivity (Schemes 2 and 3).
通过合成制备的手性助剂,即由Oppolzer樟脑衍生的sultam 4和(4-甲氧基苄基)保护的3 ,获得了一种新的,简单的,短的合成Simplactones A(1)和B(2)的途径。-羟基丙醛,总收率分别为52%和48%,并且具有非对映选择性高(方案2和3)。
