Chiral α,ω-diamines react under high-pressure conditions (10 kbar) with α,ω-dicarboxylates to give chiral cyclic tetraamides having C2-symmetry. The alkali metal (Li+, Na+, K+, Rb+, and Cs+
A new approach to the synthesis of chiral tetraazacoronands derived from L-alanine

, p. 537 - 540 (2007/10/03)
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.
