The sequential addition of functionalised chains onto a 1,2-diformylcyclopropane synthon provides rapid access to cyclopropyl oxylipins, as demonstrated here by the total synthesis of Constanolactones A–B. These eicosanoids of marine origin have been prepared in five steps, first by the regioselective γ-addition of 1-trialkylsilyloxy-1-ethoxybutadiene to (1S,2S)-1-formyl-2-(thexyldimethylsilyloxymethyl)cyclopropane
将官能化的链顺序添加到1,2-二甲酰基环丙烷合成子上,即可快速获得环丙基氧基脂,这是通过康斯坦内酯A–B的全合成证明的。这些海洋来源的类花生酸已通过五个步骤制备,首先是将(1- S,2 S)-1-甲酰基-2-(甲氧基二甲基甲硅烷氧基甲基)环丙烷的区域选择性γ加成1-三烷基甲硅烷氧基-1-乙氧基丁二烯。官能团修饰,添加(1 E,3 S,5 Z)-3-羟基不饱和烯-1,5-二烯基有机金属。
