Ethyl phenylsulfonylacetate was treated with 1,2-dibromoethane in the presence of benzyltriethylammonium chloride and alkali to give 1-phenylsulfonylcyclopropanecarboxylic acid, from which the carbonyl chloride, ester, carboxamide, 1,2-diacylhydrazine, carbonyl azide, carbamate, isocyanate, and γ-butyrolactone derivatives were prepared.
苯磺酰乙酸乙酯在苄基三乙基氯化铵和碱存在下与1,2-二溴乙烷反应,得到1-苯磺酰基环丙烷甲酸,再生成碳酰氯、酯、甲酰胺、1,2-二酰肼、叠氮羰基、氨基甲酸酯、异氰酸酯和γ制备了β-丁内酯衍生物。
