β-unsaturated amides proceeded efficiently and regioselectivity to give ω-amido esters with complete conversion in the presence of the catalyst system: Pd(PPh3)2Cl2/MeOH/CO/H2O. The reaction was successfully applied to the alkoxycarbonylation of bis-acrylamides yielding, selectively, the corresponding di-ω-amido esters. These mono and di-ω-amido esters have been used as precursors for the synthesis of N-substituted
在催化剂体系Pd(PPh 3)2 Cl 2 / MeOH / CO / H 2 O的存在下,α,β-不饱和酰胺的烷氧基羰基化有效地进行,区域选择性得到完全转化的ω-酰胺基酯。成功地将其用于双丙烯酰胺的烷氧基羰基化反应,选择性地产生相应的二ω-酰胺基酯。这些单和二ω-酰胺基酯已被用作以中等至高产率合成N-取代的环状琥珀酰亚胺的前体。
