DIASTEREOSELECTIVITY IN THE ADDITION OF ENOLATE ANIONS TO N-METHOXYCARBONYLIMINES GENERATED IN SITU FROM α-METHOXY CARBAMATES
The diastereoselectivity of the addition of enolate anions of ketones or esters to N-Methoxycarbonylimines generated in situ from α-Methoxy carbamates was studied.

Syntheses via Isoxazolines, 6. - Asymmetric Induction in the Reduction of 2-Isoxazolines to Yield γ-Amino Alcohols with Two or Three Vicinal Stereocentres
The substituted 3-aminopropanols 3 and 5 with two or three adjacent chiral centres are prepared from alkenes and nitrile oxides via LiAlH4 reduction of intermediate isoxazolines 2 and 4, respectively, in a regio- and stereoselective mode. 4-Alkyl groups g
