bis-THF-subunit preparation via Sharpless' double asymmetric dihydroxylation and subsequent asymmetric epoxidation; preparation of the C(4)-hydroxybutenolide-containing subunit using a Stille butenolide synthesis; Pdo-mediated coupling of these vinyl iodide and alkyne subunits; and selective Wilkinson reduction of the resulting enyne.
标题化合物的收敛合成包括:通过Sharpless双不对称二羟基化反应和随后的不对称环氧化反应制备双THF亚基;使用Stille丁烯内酯合成方法制备含C(4)-羟基丁烯内酯的亚基; 这些乙烯基碘和炔亚基的Pd o介导的偶联;和选择性的威尔金森还原生成的烯炔。
