with F: The title reaction proceeds using 1 mol % of the new perfluoroisopropyl chiral disulfonimide catalyst 1 to deliver several 2,6‐disubstituted and 2,5,6‐trisubstituted dihydropyrones in good yields and with excellent enantiomeric ratios. The utility of this methodology is illustrated with the first enantioselective synthesis of a potent aromatase inhibitor.
与F混合使用:使用1 mol%的新型全氟异丙基手性二磺酰亚胺催化剂1进行标题反应,以高收率和出色的对映体比率提供数个2,6-二取代和2,5,6-三取代的二氢吡喃酮。该方法的实用性通过有效的芳香化酶抑制剂的首次对映选择性合成得到了说明。
