The alkylation of the diastereomeric mixture of chiral morpholinone derivatives 4 and 5 occurs with good yield and trans induction. Cleavage of the alkylated products 6a,b,c,e gives enantiomerically pure uncommon (and sterically constrained) α,α'-dialkyl-α-aminoacids. The absolute configuration of the new stereocentres of 4, 5, 6 and 7 has been assigned on the basis of the 1H-NMR spectra and NOE measurements.
