Stereoselective cyanation of chiral α-amino aldehydes by reaction with Nagata's reagent: a route to enantiopure β-amino-α-hydroxy acids
摘要:
Chiral alpha -dibenzylamino aldehydes react with diethylaluminum cyanide leading to anti-beta -dibenzylamino-alpha -hydroxy-cyanides as the major diastereoisomers in good yields and diastereomeric excesses. Hydrolysis of the nitrile derivatives allows the synthesis of enantiopure beta -amino-alpha -hydroxy acids. (C) 2001 Elsevier Science Ltd. All rights reserved.

Unique Stereocontrol in Europium(III)-Catalyzed Cyanosilylation of Chiral α-Alkoxy and α-Amino Aldehydes
The Eu(III)-catalyzed cyanosilylations of chiral α-alkoxy and α-amino aldehydes are shown to exhibit syn diastereofacial selection, the degree increasing with an increase in steric bulk of the alkyl chain in the aldehydes. The mechanism of this catalytic process is discussed.
