the C(1)-C(11) fragment 4 of peloruside A has been accomplished via a stereoselective double allylboration and an intramolecular epoxide opening to provide the functionally dense C(3)-C(11) segment 14. A glycolate aldol reaction was then employed to introduce the remaining stereocenters at C(2)-C(3). [reaction: see text]
球果甙A的C(1)-C(11)片段4的高度立体选择性合成是通过立体选择性双烯丙基硼化和分子内环氧化物开口完成的,以提供功能上密集的C(3)-C(11)片段14。然后采用乙醇酸酯羟醛反应在C(2)-C(3)处引入其余的立体中心。[反应:看文字]
