Wh. Miller et al., ENANTIOSPECIFIC SYNTHESIS OF SB-214857, A POTENT, ORALLY-ACTIVE, NONPEPTIDE FIBRINOGEN RECEPTOR ANTAGONIST, Tetrahedron letters, 36(52), 1995, pp. 9433-9436
An enantiospecific synthesis of SE 214857, a potent, nonpeptide fibrin
ogen receptor antagonist, is reported. The synthetic route employs as
a key step an intramolecular aryl fluoride displacement to form the se
ven-membered ring of the 1,4-benzodiazepine system.
