Abstract

Dimethyl α,ω-dicarboxylates react under high pressure or ambient conditions with chiral primary diamino ethers derived from L-alanine to give the chiral cyclic diamides or tetramides in satisfactory yields. The effective preparation of chiral amino components starting from L-alanine is also described.
