Catalytic enantioselective routes to bifunctional C5 synthons, including those of the macrolide (S)-(−)-zearalenone have been achieved. Stereochemistry was introduced using a mixed ligand arene chromium tricarbonyl catalyst to mediate the enantioselective addition of dimethyl zinc to a functionalized aldehyde. Comparison with alternate reduction strategies is presented.
已实现了双官能C5合成子的催化对映选择性路线,包括大环内酯(S)-(-)-玉米赤霉烯酮的合成。使用混合的配体芳烃铬三羰基催化剂引入立体化学,以介导二甲基锌向官能化醛的对映选择性加成。提出了与其他减少策略的比较。
