  将有机催化与光有机催化结合：不对称有机催化迈克尔加成产物的光催化加氢酰化†

  摘要：

  有机催化和光有机催化是已在有机合成中得到广泛应用的合成方法的两个领域。本文中，我们报告了这两种状态的组合，其中第一步是将α，α-二取代的醛有机催化加成到马来酰亚胺，第二步是将偶氮二羧酸二异丙酯进行光催化加氢酰化。利用氨基酸作为不对称有机催化部分的有机催化剂，并利用有机分子作为光催化剂，这两种策略的结合产生了所需的产物。许多烷基和芳基取代的马来酰亚胺已被成功使用，而该规程可用于α，α-二取代的醛，从而以中等至高收率（44–84％）和出色的对映选择性（98–100％ee）产生产品）。

The combination of the catalytic unit, the triazole linker, and the polymeric matrix provides unprecedented substrate selectivity, in favor of linear, short‐chain aldehydes, when the organocatalyzed reaction proceeds by an enamine mechanism. High versatility is noted in reactions that proceed via an iminium
