Zusammenfassung

The diketopiperazine cyclo(-L-Val-Gly-) (1) can be 0-alkylated under mild acidic reaction conditions with the alkyl trichloroacetimidates 2 to the corresponding bisalkyl bislactim ethers. Alkylation of the bisbenzyl bislactim ether anion of cyclo(-L-Val-Gly-) 4 c with benzyl bromide and subsequent hydrolysis with aqueous trifluoroacetic acid afforded D-phenyl-alanine benzyl ester (8) with an enantiomeric excess of >95%.
