A simple synthesis of tricyclic analogues of the quinolone antibiotics bearing a diverse range of substituents on the aromatic ring is described. The key steps involve unprecedented Reformatsky reaction between diethyl bromomalonate and N-arylpyrrolidine-2-thiones 8, followed by cyclisation of the resulting enaminone intermediates 9 in polyphosphoric acid.
A platelet aggregation inhibitor comprising a quinolone derivative or a pharmaceutically acceptable salt thereof as an active ingredient, and a novel quinolone derivative or a pharmaceutically acceptable salt thereof useful as a platelet aggregation inhibitor.
