Synthesis of a versatile 2 (1H)-pyrazinone core for the preparation of Tissue Factor-Factor VIIa inhibitors
摘要:
A new, general synthetic route to 2(1H)-pyrazinones 11 is described The four-step synthesis is accomplished utilizing a regioselective hydrolysis and N-alkylation These compounds efficiently undergo metal-catalyzed cross-coupling reactions to install P2 diversity groups in the 6-position, which can be used to refine the SAR of the S2 pocket of the Tissue Factor/Factor VIIa (TF/VIIa) complex (C) 2010 Elsevier Ltd All rights reserved
The rates of gas-phase elimination of N-ethyl (1), N-isopropyl (2), N-t-butyl (3) substituted 2-aminopyrazine and N-ethyl (4), N-isopropyl (5), and N-t-butyl (6) substituted 2-aminopyrimidine have been measured. The compounds undergo unimolecular first-order pyrolytic reactions. The relative rates of the primary:secondary;tertiary alkyl homologues at 600 K are 1:14.4:38.0 for the pyrazines and 1:20
