A rapid and diastereoselective method was developed for the [2,3]-sigmatropic rearrangement of N-Allyl ammonium ylides, affording products in up to 95percent isolated yields and up to 97:3 dr; most of the desired products were formed within 1 minute. For

Benzotetramisole promotes the catalytic asymmetric [2,3]-rearrangement of allylic quaternary ammonium salts (either isolated or prepared in situ from p-nitrophenyl bromoacetate and the corresponding allylic amine), generating syn-α-amino acid derivatives with excellent diastereo- and enantioselectivity (up to >95:5 dr; up to >99% ee).
