Expeditious synthesis of (R)-bicalutamide (1), a synthetic antiandrogen, from enantiopure 2-methylpropane-1,2,3-triol monobenzyl ether (4) was achieved. An engineered Bacillus subtilis epoxide hydrolase worked enantioselectively on the racemic epoxide (7) to provide the above starting material in highly enantiomerically enriched state.
从对映纯的2-甲基丙烷-1,2,3-三醇单苄基醚(4)迅速合成了合成的抗雄激素(R)-比卡鲁胺(1)。工程化的枯草芽孢杆菌环氧水解酶在外消旋环氧化物(7)上对映选择性地工作,以高度对映体富集的状态提供上述起始原料。
