✦ Synopsis

Synthesis of New Enantiopure γ-Amino Alcohols: Their Use as Catalysts in the Alkylation of Benzaldehyde by Diethylzinc.

-Seven γ-amino alcohols are prepared by a convenient method based on 1,3-dipolar cycloaddition of the nitrone (I) to olefins. Among them the alcohols (VI) and (VIIa) are best catalysts in zinc mediated alkylation of benzaldehyde. However, only modest enantioselectivity is observed.
