The total synthesis of (+)-papuamine, the antipode of the C(2)-symmetric, optically active, pentacyclic diamine natural product, starting from a chiraldiol is described. The diol is available via an asymmetric Diels-Alder reaction between 1,3-butadiene and di-(-)-menthyl fumarate. The keytransformation in the synthesis is an intramolecular Pd(0)-catalyzed (Stille) coupling reaction to form the central

The present invention relates to the new [6+5] fused bicycle derivatives, pharmaceutically acceptable salts or isomers thereof, processes for preparing the same, and pharmaceutical compositions comprising the same. The [6+5] fused bicycle derivatives can antagonize the thrombin receptor and thus may be effectively used for the treatment and prevention of thrombus, platelet aggregation, atherosclerosis, restenosis, blood coagulation, hypertension, arrhythmia, angina pectoris, heart failure, inflammation and cancer when used alone or with other cardiovascular agents.
