4-dihydropyridines via an acyl radical addition and hydrogen atom transfer pathway under photocatalyst-free conditions. The efficiency was highlighted by wide substrate scope, good to high yields, successful scale-up experiments, and expedient preparation of highly functionalized ketone derivatives. In addition, this protocol allows for the synthesis of 1,4-dicarbonyl compounds through alkene diacylation in the presence
在这里,我们描述了一种可见光促进的加氢酰化策略,该策略有助于在无光催化剂的条件下,通过酰基加成和氢原子转移途径,从烯烃和4-酰基-1,4-二氢吡啶制备酮。广泛的底物范围,良好至高收率,成功的按比例放大实验以及方便地制备高度官能化的酮衍生物等突出了效率。另外,该方案允许在NiCl2·DME存在下通过烯烃二酰化反应合成1,4-二羰基化合物。
