Significance

(+)-Chamaecypanone is one of several bicyclo[2.2.2]octenone natural products that have been isolated from Chamaecyparis obtuse var. formosana. (+)-Chamaecypanone has good activity (IC50 = 190nM) against human epidermoid carcinoma. The authors describe a retro-Diels-Alder/Diels-Alder pathway to the natural product.
