Stereoselective totalsynthesis of (+)-tanikolide, a bioactive δ-lactone marine natural product, was successfully accomplished by using regioselective HBr elimination reaction of 3-acyloxy-1,2-dibromoalkanes, Pd-mediated coupling reaction, and the Sharpless asymmetric epoxidation as key steps.
Total synthesis of (+)-tanikolide, a bioactive δ-lactone of marine origin, was successfully accomplished by utilizing a bromoalkene derivative conveniently synthesized from the corresponding 1-acyloxy-2,3-dibromoalkane by the regioselective and mild HBr-elimination reaction, along with the Pd-mediated C–C coupling reaction and the Sharpless asymmetric epoxidation as key steps.
