A novel, efficient Z-alkene synthesis via photocatalyzed decarboxylative couplings between terminal aryl alkynes and alkyl N-hydroxyphthalimide (NHPI) esters, which are derived from aliphatic carboxylic acids, is described. A wide range of primary, secondary, and tertiary carboxylates as well as α-amino acid and α-oxyacid-derived esters were employed as suitable substrates. The mild reaction conditions
描述了通过末端芳基炔烃和衍生自脂族羧酸的烷基N-羟基邻苯二甲酰亚胺(NHPI)酯之间的光催化脱羧偶联的新颖,有效的Z-烯烃合成。各种各样的伯,仲和叔羧酸盐以及α-氨基酸和α-含氧酸衍生的酯被用作合适的底物。温和的反应条件,广泛的底物范围,官能团耐受性和操作简便性使得该脱羧偶联反应成为有机合成中的重要方法。
