6]decane derivatives is reported. An efficient enzymatic kinetic resolution is employed through transesterification in the presence of lipase PS immobilized on Celite. Absolute configuration of the tricyclo[5.2.1.02,6]decan-10-one derivatives has been secured through correlation with (1R,2S)-1-aminoindan-2-ol.
