Stereoselective conjugate addition of organocuprates to a dehydroalanine derived diketopiperazine
Bull SD., Davies SG., O'Shea MD.
An asymmetric synthesis of homochiral α-amino acids has been developed which is based on the conjugate addition of organocuprates to the dehydroalanine equivalent (3S)-N,N′-bis(p-methoxybenzyl)-3-isopropyl-6-methylenepiperazine-2,5-dione 6.
