Going cyclic! A catalytic cycle and cyclic transition states enable a novel sustainable and catalytic hydrogen atom transfer (HAT) for highly diastereoselective radical reductions. Readily available nontoxic silanes are the terminal reductants for epoxides that are opened by bifunctional titanocene(III) hydride catalysts.
去循环!催化循环和环过渡态使能高度非对映自由基减少一个新型可持续和催化氢原子转移(HAT)。容易得到的无毒的硅烷是由双官能二茂钛(III)氢化催化剂打开环氧化物的终端还原剂。
