amphidinolide B1 have been accomplished. The 1,3-isomerization of allylic alcohol 10 was accomplished via rhenium oxo catalysis and has been applied successfully in the synthesis. (-)-MIB-catalyzed asymmetric vinylzinc addition to aldehyde 31 and the regio- and stereoselective epoxidation of unsymmetrical divinyl methanol 32 were key steps.
[结构:见文字]。两性霉素B1的三个片段2、3和4的合成已经完成。烯丙基醇10的1,3-异构化是通过rh氧羰基催化完成的,并已成功地用于合成中。除醛31外,(-)-MIB催化的不对称乙烯基锌以及不对称二乙烯基甲醇32的区域和立体选择性环氧化是关键步骤。
