04 - 213Synthesis of 6-Amino Acid Substituted 4,6,7,12-Tetrahydro-4-oxoindolo[2,3-a]quinolizines. — Acid-catalyzed cyclization of N-dioxobutyl-substituted tetrahydrocarboline (I) followed by esterification withN-Boc-protected amino acids (IV) provides the title tetrahydrooxoindolo-quinolizines (V) in good yields. The anticancer activity of the newly formedderivatives is screened. — (ZHAO, MING; WANG, CHAO; GUO, MIN;PENG, SHIQI; WINTERFELDT, EKKEHARD; J. Prakt. Chem. 341 (1999)7, 691-694; Sch. Pharm.
