The C-18–C-34 fragment of amphidinolides C, C2, and C3 and the C-18–C-29 fragment of amphidinolide F have been constructed from a trans-2,5-disubstituted dihydrofuran. This key intermediate was prepared from a dihydrofuranone formed by diastereoselective rearrangement of a free or metal-bound oxonium ylide generated from a metal carbenoid. The side chains found in amphidinolides C and F were introduced
安非他命C,C2和C3的C-18–C-34片段和安非他命F的C-18–C-29片段是由反式-2,5-二取代的二氢呋喃构建的。该关键中间体是由二氢呋喃酮制得的,该二氢呋喃酮是由金属类化合物生成的游离的或与金属结合的氧鎓叶立德进行非对映选择性重排而形成的。使用Sonogashira偶联反应引入在两性霉素C和F中发现的侧链。
