The stereoselective total synthesis of (-)-panaxjapyne-C was accomplished in a convergent fashion. The synthesis utilizes the readily available enantiomers L-(+)-diethyltartrate and D-(-)-diethyltartrate and involves a Cadiot-Chodkiewicz coupling reaction, and an Ohira-Bestmann reaction as the key steps.

First stereoselective total synthesis of panaxjapyne C
The first stereoselective totalsynthesis of polyacetylene panaxjapyne C is described. The key reactions include regioselective opening of the epoxide and Cadiot–Chodkiewicz cross-coupling reactions. l-Ascorbic acid was used as a chiral pool material for the construction of the both terminal acetylenes.
