Popis: A concise, stereoselective synthesis of α-substituted γ-lactams is reported. γ-Lactam scaffolds 2 and 3, possessing an Evans' chiral auxiliary and two types of N substituents, were successfully alkylated with different electrophiles to give α-substituted γ-lactams with reasonable diastereoselectivities. The use of a masked carboxymethyl function off the lactam nitrogen provided a convergent means to α-substituted γ-lactam dipeptide isosteres.
