[reaction: see text] Highly diastereoselective syntheses of diketo esters 6a and 6b are described. These intermediates undergo efficient aldol reactions with protected C(13)-C(21) aldehydes 3 and 23, thereby providing advanced C(1)-C(21) tedanolide seco ester precursors 9a and 9b.
[反应:见正文]描述了二酮酯6a和6b的高度非对映选择性合成。这些中间体与受保护的C(13)-C(21)醛3和23进行有效的羟醛反应,从而提供高级的C(1)-C(21)tedolide seco酯前体9a和9b。
