A Simple Method for Chelation Controlled Additions to α-Amino Aldehydes
Reetz, Manfred T.,Roelfing, Karin,Griebenow, Nils
, p. 1969 - 1972 (1994)
BOC- and Cbz-protected α-amino aldehydes derived from amino acids undergo stereoselective addition reactions with alkyl cuprates and manganese reagents, the chelation-controlled adducts being the major diastereomers (generally ds > 90percent).Undesired ra
