1) ethyl arylglyoxylate
芳基乙酮酸乙酯
1.
By the Friedel-Crafts acylation reaction with aromatic compounds 1a～1h and ethyl oxalyl chlo-ride as the starting materials,eight ethyl arylglyoxylates 2a～2h have been synthesized,and their structures were confirmed by IR,1H NMR spectra and elemental analyses.
以芳烃和草酰氯单乙酯为原料,采用Friedel-Crafts酰基化反应合成了8种芳基乙酮酸乙酯,用IR,1H NMR,元素分析确认了合成化合物结构,并用高效液相色谱法分析了反应的选择性。
2) substitutional acetophenone
芳基乙酮
1.
Eight of corresponding aryl acetic acids were synthesized from series substitutional acetophenone through Willgerodt-Kindler reset and hydrolysis reaction.
以各种芳基乙酮为原料,通过Willgerodt-Kindler重排反应、水解反应合成了8个相应的芳基乙酸类化合物。
3) arylsulfonylacetate
芳磺酰基乙酸酯
1.
The effects of substistution groups at the phenyl ring of reactant-arylsulfonylacetates on the addition-rearrangement reaction were examined.
研究了反应物-芳磺酰基乙酸酯苯环上取代基对加成-重排反应的影响,发现只有当芳环上4位或2位有硝基时,在K2CO3-TEBA相转移催化体系中,芳磺酰基乙酸酯与α,β-不饱和酯反应才可发生加成-重排反应,生成2-芳基戊二酸酯,其机理可能是芳磺酰基乙酸酯与α,β-不饱和酯首先发生Michael加成反应,随后加成产物发生分子内的亲核取代,酸化后脱去SO2得2-芳基戊二酸酯。
4) ethyl 3-arylpropionate
