combination of an aldehyde, an allylic bromide, and tert-butanesulfinamide in the presence of indium metal and titanium tetraethoxide allows straightforward access to homoallylamine derivatives in high yields and stereoselectivities. Moreover, the synthetic utility of the enantioenriched homoallylamine derived from n-decanal was illustrated in a concise synthesis of (+)-isosolenopsin. In this context, similar

Base-inducedcyclization of enantiopure (2-aminoalkyl)oxiranes allowed the stereospecific formation of pyrrolidin-3-ols and/or 2-(hydroxymethyl)azetidines, depending on the reaction conditions. The oxidation of 2-(hydroxymethyl)azetidines led to azetidine-2-carboxylic acids in high yields.

The totalsynthesis of tubulysinV 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
