The invention relates to a novel compound which is represented by the formula (1) and has an excellent platelet aggregation inhibiting action based on fibrinogen antagonism. The platelet aggregation inhibitor containing the compound of the formula (1) as an effective ingredient is effective for prevention and therapy of thrombosis and restenosis or reocclusion after percutaneous transluminal coronary angioplasty or percutaneous transluminal coronary recanalization.
natural products. However, efficient and environmentally friendly approaches to accessing spirolactones are still highly desirable. Herein, a novel electrochemical synthesis of spirolactones from α-tetralone derivatives with methanol as a C1 source is described. This electrochemical reaction exhibits a high efficiency and good functional group tolerance.

The invention relates to a novel compound which is represented by the formula (1) and has an excellent platelet aggregation inhibiting action based on fibrinogen antagonism. The platelet aggregation inhibitor containing the compound of the formula (1) as an effective ingredient are effective for prevention and curing of thrombosis and restenosis or reocclusion after percutaneous transluminal coronary angioplasty or percutaneous transluminal coronary recanalization.
and economical one-pot approach to chiral fused tricyclic lactams from readily available ketoesters was developed by using cheap ammonium salts as the nitrogen source through ruthenium-catalyzed tandem dynamic kinetic asymmetric reductive amination/lactamization. This protocol provides highly efficient access to drug intermediates and organocatalysts containing chiral polycyclic N-heterocycles.
