An asymmetric approach to key intermediate 17 starting from lactone 7 is described, in which Evan’s alkylation and CBS-catalyzed reduction are used for construction of the chiral centers, respectively. Thus, the synthesis of (E)-dehydroapratoxin A 6 could be accomplished in a general fashion, therein FDPP has been proven as an efficient condensation reagent for the coupling of amine 25 and carboxylic
描述了一种从内酯7开始的关键中间体17的不对称方法,其中将Evan烷基化和CBS催化的还原分别用于手性中心的构建。因此,(E)-脱氢戊糖毒素A 6的合成可以以一般方式完成,其中FDPP已被证明是用于胺25和羧酸24偶联的有效缩合剂。
