A concise and modular total synthesis of the highly potent N14-desacetoxytubulysin H (1) has been accomplished in 18 steps in an overall yield of up to 30percent. Our work highlights the complexity-augmenting and route-shortening power of diastereoselective multicomponent reaction (MCR) as well as the role of bulky ligands to perfectly control both the regioselective and diastereoselective synthesis of tubuphenylalanine in just two steps. The total synthesis not only provides an operationally simple and step economy but will also stimulate major advances in the development of new tubulysin analogues.

The total synthesis of tubulysin V was accomplished in 1.0% overall yield with linear 13 steps. Our synthetic strategy featured the following two reactions. One is zinc-mediated aza-Barbier reaction of (R)-N-tert- butanesulfinyl imine 8 with β-ester group functionalized allylic bromide 9 to afford the chiral homo-allylic amine (7); the other is to employ the methodology of aqueous indium-mediated aza-Barbier reaction previously developed by our group, giving the chiral homo-allylic amine 13 with high efficiency.
