A Boron‐Based Synthesis of the Natural Product (+)‐trans‐Dihydrolycoricidine

Abstract
Diastereoselective diboration results in the highly selective 1,4‐dihydroxylation of chiral cyclohexadienes (see scheme). Together with the catalytic enantioselective conjugate allylboration, the diene diboration facilitates the asymmetric synthesis of the cytotoxic agent (+)‐trans‐dihydrolycoricidine (1 ). pin=pinacol.
