C. Fernandezgarcia et al., SOLID-PHASE SYNTHESIS OF N-CARBOXY ALKYL-CONTAINING PEPTIDES DERIVED FROM ENANTIOPURE ALPHA-KETO-BETA-AMINO-ACIDS, Bioorganic & medicinal chemistry letters, 8(5), 1998, pp. 433-436
alpha-Keto-beta-aminoacids 5a-c can be reductively aminated with the p
eptide sequence H2N-Leu-Val-Phe-Phe on a solid support to afford N-car
boxy alkyl peptides la-c. The N-carboxy alkyl lysine derivative 7 was
subsequently extended from the N-terminus with glutamine and histidine
residues. (C) 1998 Elsevier Science Ltd. All rights reserved.
