Stereoselective Nitrilimine Cycloadditions to the C=N Bond of Enantiopure
— The reaction between hydrazonyl chlo14- 139 N-(1-Phenylethyl)-1-arylmethanimines.
rides (I) and imines (II) in the presence of triethylamine proceeds via in situ generation
of nitrilimines from (I). Their regioselective addition to the imines gives triazoles
(III)/(IV). Major products (III) are formed with low to fair diastereoselectivities. —
