A convergent synthesis of the spiroketal subunit of rutamycins A and B has been devised via Julia coupling of sulfone 14 with aldehyde 23; the pentahydroxy ketone 3 derived from 25 underwent spontaneous cyclization to spiroketal 4.
通过砜14与醛23的朱莉娅偶联设计了芸霉素A和B的螺环亚单位的收敛合成; 从25衍生的五羟基酮3自发地环化成为spiroketal 4。
