EBC-23 (2), a prostate anticanceragent, was isolated from the fruit of Cinnamomum laubatii (family Lauraceae) in the Australiantropicalrainforest. Extensive NOE experiments enabled the relative stereochemistry of the proposed EBC-23 (2) structure to be determined. Total synthesis of both enantiopodes over nine linear steps, involving challenging RCM and spiroacetal cyclizations, confirmed the gross
