A convenient method for the synthesis of eight alkyl 6-[4,5-dihydroisoxazol-3-yl(-pyrazol-3(5)-yl)]hexanoates from the cyclocondensation of methyl 10,10,10-trifluoro[chloro]-9-oxo-7-methoxydec-7-enoates and hydroxylamine hydrochloride or hydrazine hydrochloride, respectively, in ethanol as solvent is reported. The reaction of methyl 10,10,10-trichloro-9-oxo-7-methoxydec-7-enoates with hydrazines furnished
从10,10,10-三氟[氯]-甲基的环缩合反应合成八种烷基6- [4,5-二氢异恶唑-3-基(-吡唑-3(5)-基)]己酸酯的简便方法据报道,在乙醇作为溶剂中分别存在9-氧代-7-甲氧基癸-7-烯酸酯和盐酸羟胺或盐酸肼。10,10,10-三氯-9-氧代-7-甲氧基dec-7-烯酸酯的甲基与肼的反应提供了吡唑衍生物,同时三氯甲基转化为羧基。
