To synthesize a tripeptide derivative Phac-Met-Asp(OMe)-Phe -NH2, which is a fragment of the gastrin C-terminal tetrapeptide CCK-4, by enzymatic reaction. Three free enzymes, alpha-chymotrypsin, papain and thermolysin from acyl donor Phac-Met-OCam was involved in three steps. The choice of appropriate

A facile and economical synthesis of a novel orally active 1-beta-methylcarbapenem, TA-949 (1), is described. The key process involves an efficient synthesis of the C-2 side chain (R)-4-mercaptopyrrolidine-2-thione 2 from L-aspartic acid and the construction of the 1-beta-methylcarbapenem skeleton. The
