Herein, a new substrate-controlled hydrogenation of flavanones to selectively obtain 2′-hydroxy-1,3-diarylpropanes or flavans depending on the substitution of the flavanone moiety is described. Thus, hydrogenation of non-fluorinated flavanones provided the corresponding 2′-hydroxy-1,3-diarylpropanes, whereas hydrogenation of fluorinated flavanones afforded selectively the corresponding flavans in excellent
在此,描述了一种新的底物控制的黄烷酮氢化,根据黄烷酮部分的取代选择性地获得 2'-羟基-1,3-二芳基丙烷或黄烷。因此,非氟化黄烷酮的氢化提供了相应的 2'-羟基-1,3-二芳基丙烷,而氟化黄烷酮的氢化以优异的产率选择性地提供了相应的黄烷。
