The MgCl2-enhanced addition of benzyl zinc reagents to N-tert-butanesulfinyl imines proceeds readily at room temperature to afford the N-tert-butanesulfinyl-protected amine products in good yields and diastereomeric ratios. This method is functional group tolerant in both the imine substrate and benzyl zinc coupling partner. Moreover, benzyl zinc reagentaddition to the N-tert-butanesulfinyl imine

New 3-N-acyl derivatives of 3-amino-2-hydroxy-4-phenylbutanoic acid are provided, which exhibit analgesic activity and are effective to enhance the morphine analgesia.
Ring-opening reactions of optically active cis-disubstituted aziridino alcohols have been investigated. Regio- and stereo-selective ring opening took place with internal and external nucleophiles. Unusual amino acids derivatives (14) and (15), the key synthetic intermediates for bestatin and related peptides, have been prepared.
