ABSTRACT
The asymmetric total synthesis of (+)-crassalactone D (4), a naturally occurring antitumor agent, has been achieved by employing an oxidative spirocyclization of furan 11 as the key step. Two close analogues, 7-epi-crassalactone D (14) and 5-epi-7-epi-crassalactone D (15), also have been prepared in the course of the synthesis of (+)-crassalactone D.

ABSTRACT
Introduction of the phenyl piperidinone and phenyl pyridinone P4 moieties in the anthranilamide scaffold led to potent, selective, and orally bioavailable inhibitors of factor Xa. Anthranilamide 28 displayed comparable efficacy to apixaban in the rabbit arteriovenous-shunt (AV) thrombosis model.
