1,3-Asymmetric induction in the Et 2 Zn-catalyzed addition of terminal alkynes was studied with nitrones bearing a chiral auxiliary on their nitrogen atom. The obtained propargylic N-hydroxylamines were generally isolated in good yields and with satisfactory to excellent diastereoselectivities.

An InBr 3 -catalyzed direct and efficient alkynylation of nitrones with terminal alkynes was developed. The process enables practical synthesis of a wide range of synthetically useful N-hydroxy-propargyl amine derivatives in good yields under mild conditions. The application of this method to optica
