β-unsaturated carbonyl compounds using methyl 3-methoxyacrylate, methyl 3,3-dimethoxypropionate, or 1,1-dimethoxy-3-butanone is reported. 35% HCl aqueous solution catalyzes this reaction efficiently in acetic acid. One of the most favorable substrates is 3-(4-fluorophenyl)-1-isopropyl-1H-indole, which reacts nearly quantitatively to give the corresponding α,β-unsaturated ester, and the scope of the reaction
据报道,使用3-甲氧基丙烯酸甲酯,3,3-二甲氧基丙酸甲酯或1,1-二甲氧基-3-丁酮进行酸催化的3-吲哚基α,β-不饱和羰基化合物的合成。35%HCl水溶液在乙酸中有效催化该反应。最有利的底物之一是3-(4-氟苯基)-1-异丙基-1 H-吲哚,它几乎定量地反应生成相应的α,β-不饱和酯,并且反应范围可以扩大到一定程度。富电子苯衍生物。
