Enantioselective synthesis of 2, a revised structure for (-)-clavosolide B, was accomplished by a convergent approach, where syn-selective aldol, hydroxy-directed cyclopropanation, Mitsunobu inversion, Schmidt-type glycosylation, and macrolactonization reactions were utilized as key reactions. Comparison of 1H and 13C NMR spectra and optical rotation measurement confirmed the relative and absolute
对映选择性合成2,即修订为(-)-clavosolide B的结构,通过收敛方法完成,其中同选择性醛醇,羟基定向环丙烷化,Mitsunobu倒置,Schmidt型糖基化和大内酯化反应被用作关键反应。1H和13C NMR光谱和旋光度测量的比较证实了clavosolide B的相对和绝对立体化学(2)。
