(AB) crotylstannane with the C15C28 (CD) aldehyde followed by stereochemical arrangements gave the C1C28 (ABCD) fragment of altohyrtin C. The C29C44 (EF) fragment was also prepared. The syntheses of these two fragments, both of which were identical with those prepared by the Smith group, constitute a formal total synthesis of altohyrtin C.
将C1C14(AB)巴豆基锡烷与C15C28(CD)醛偶联,然后进行立体化学排列,得到altyryrtin C的C1C28(ABCD)片段。还制备了C29C44(EF)片段。这两个片段的合成均与史密斯小组制备的片段完全相同,构成了altohyrtin C的正式全合成。
