Stereoselective total synthesis of tubulysin v

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.

Stereoselective synthesis of 2-alkenylaziridines and 2-alkenylazetidines by palladium-catalyzed intramolecular amination of α- and β-amino allenes

Whereas palladium-catalyzed reaction of N-arylsulfonyl-α-amino allenes with an aryl iodide (4 equiv) in the presence of potassium carbonate (4 equiv) in DMF at around 70 °C affords the corresponding 3-pyrroline derivatives, the reaction in refluxing 1,4-dioxane under otherwise identical conditions yields exclusively or most predominantly the corresponding 2-alkenylaziridines bearing an aryl group on the double bond. Similarly, N-arylsulfonyl-β-amino allenes can be also cyclized into the corresponding alkenylazetidines bearing a 2,4-cis-configuration under palladium-catalyzed cyclization conditions in DMF.
