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.
