The reactions of the title compound with hydrazines are studied to shed light on the course of the reaction of γ-alkoxyfuran-2(5H)-ones with these binucleophiles. At room temperature, both unsubstituted hydrazine and phenylhydrazine in ethanol, or hydrazine and its methylderivative in ethanol–acetic acid, afforded good yields of 5-amino-, 5-phenylamino-, and 5-methylamino-6-hydroxy-3-methyl-3a,5,6
研究了标题化合物与肼的反应以阐明γ-烷氧基呋喃-2(5 H)-酮与这些双亲核试剂的反应过程。在室温下,乙醇中的未取代肼和苯肼,或乙醇-乙酸中的肼及其甲基衍生物,均能获得5-氨基-,5-苯基氨基-和5-甲基氨基-6-羟基-3-甲基-的良好收率。 3a,5,6,6a-四氢-4 H-吡咯并[3,4- d ]异恶唑-4-酮。在室温下,只有甲基肼在乙醇中生成异恶唑并[4,5- d ]哒嗪-4(3a H)-1体系的衍生物。没有从苯肼获得哒嗪酮衍生物。
