    isoflavone epoxidation as illustrated for the substrate 3c. This fact indicates the pivotal role of the hydroxy group for enantioselective control, which is rationalized in terms of a hydrogen-bonded aggregate between the ether-oxygen atom of isoflavone 3 and the phase-transfer catalyst 1. The present attractive and convenient method should be useful for the preparation of optically active epoxides of
    异黄酮3的不对称Weitz-Scheffer环氧化反应是由辛可宁和辛可尼定衍生的相转移催化剂(PTCs)1介导的,提供的对映异构体富集的异黄酮环氧化物4的ee值几乎定量,产率高达98%。使用适当配置的PTC 1,可以通过使用市售的枯基氢过氧化物2b作为氧化剂来获得异黄酮环氧化物的两种对映异构体。最有效的PTC(1b)中羟基官能团的甲基化会大大降低异黄酮环氧化的对映选择性,如底物3c所示。这一事实表明了羟基在对映选择性控制中的关键作用,这通过异黄酮3的醚-氧原子与相转移催化剂1之间的氢键结合的聚集体得以合理化。

    4-Aryl-3(5)-2-(hydroxyphenyl)pyrazoles have been prepared by the reaction of isoflavones and their 4-thio analogues with hydrazine hydrate and phenylhydrazine in hot pyridine. The reaction mechanism for the formation of these pyrazoles is discussed. All the new compounds have been fully characterized by NMR spectroscopy. In [D6]DMSO, a 1H NMR study allows observation of the presence of both pyrazole annular tautomers

    The comparative epoxidation of 2-substituted isoflavones 9–16 has been conducted by the utilization of three different protocols, viz. epoxidation with isolated dimethyldioxirane (Method A), with sodium hypochlorite (Method B), and with alkaline hydrogen peroxide (Method C), to afford epoxides 17–24. Best results have been obtained with Method C (Weitz-Scheffer epoxidation). The structures of epoxides
    2-取代异黄酮9-16的比较环氧化反应是通过利用三种不同的方法进行的,即。用分离的二甲基二环氧乙烷(方法A),次氯酸钠(方法B)和碱性过氧化氢(方法C)进行环氧化,得到环氧化物17-24。使用方法C(Weitz-Scheffer环氧化)已获得最佳结果。环氧化物的结构已基于核磁共振光谱和质谱数据确定。
