efficient stereoselective synthesis of the C14–C29 fragment highlighting a coupling reaction between a 1,3-dithiane derivative and an α-branched aldehyde was realized. This highly convergent synthesis involved two chiral pools, L-malic acid and (+)-camphorsulfonic acid, which are the starting compounds to control the six stereogenic centers present in the C14–C29 fragment of amphidinol 3.
实现了C14-C29片段的高效立体选择性合成,突出了1,3-二硫杂环丁烷衍生物与α-支链醛之间的偶联反应。这种高度趋同的合成涉及两个手性库,L-苹果酸和(+)-樟脑磺酸,这是控制两性酚C14-C29片段中六个立体异构中心的起始化合物。
