A new double asymmetric induction in carbon-carbon bond formation is -achieved by the use of palladium chiral complexes in the alkylation of chiral Schiff bases1 derived from glycine. High diastereoisomeric excesses are obtained (90-999) using N.N-cyclohexylsulfamoylisobornyl derivatives and DIOP as

For the purpose of practical preparations of a variety of enantiomerically pure uncommon Β’x-amino acids, alkylations of the chiral glycine equivalent 5, which possesses axially chiral binaphthol as an auxiliary, with several electrophiles were investigated. The alkylation proceeded smoothly in satis
