A copper(II)-catalyzed 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU)-mediated synthesis of α-acyloxyacetates from α-azidoketones and diazoacetates under visible light at room temperature is described. This reaction involves an oxidative esterification process, leading to the formation of two new C–O bonds with the elimination of dinitrogen molecules in the overall process. 20 examples of α-acyloxyacetates
描述了铜( II )催化的1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)介导的在室温下可见光下由α-叠氮酮和重氮乙酸酯合成α-酰氧基乙酸酯的方法。该反应涉及氧化酯化过程,导致形成两个新的C-O键,并在整个过程中消除二氮分子。通过将各种 α-叠氮酮与重氮乙酸酯偶联,以高产率 (70-86%) 合成了 20 个 α-酰氧基乙酸酯。含有给电子基团(Me、MeO)、吸电子基团(CN、NO 2 )、卤素原子(Cl、Br)和其他芳基的α-叠氮酮与各种取代的重氮乙酸酯(乙基、叔丁基、苄基)相容),导致形成α-酰氧基乙酸酯。
