The absolute configuration of the antibiotic (+)‐xanthocidin (4,5‐dihydroxy‐5‐isopropyl‐4‐methyl‐2‐methylene‐3‐oxocyclopentane‐1‐carboxylicacid, 1 ) was shown to be 1 R ,4 S ,5 S by the synthesis of its enantiomers. Lipase AK (Amano) was used for the key resolution step, and the absolute configuration of the resolved intermediate (+)‐ 16 was determined by the X‐ray analysis of its (1 S )‐camphanic ester (+)‐ 20 .
