Tubulysin V has been enantioselectively synthesized from the units of dipeptide 23, Tuv and Tup. The features of this synthetic strategy is included three portions, the Tuv fragment 17 was diastereoselectively synthesized from the d-malic acid, the stereocenters of the Tup unit was constructed by the asymmetric reduction as well as methylation, and the epimerization for several known methods was successfully
已经从二肽23,Tuv和Tup的单元对映选择性地合成了TubulysinV 。该合成策略的特征包括三部分:从d-苹果酸非对映选择性地合成Tuv片段17,通过不对称还原和甲基化构建Tup单元的立体中心,几种已知方法的差向异构化是通过片段19与24的缩合以及氢化脱保护而成功避免了这种情况。
