New compounds of N-(substituted thio) isatins (III) were synthesized and reactions with several nucleophiles were examined in comparison with the reaction using N-(substituted thio) phthalimides (I) and N-(substituted thio) succinimides (II) : All of I, II, and III reacted with organometallic compounds, cyanide ion, and trichloromethyl carbanion to give sulfides (IV), thiocyanates (V), and trichloromethyl sulfides (VI) respectively. Different from I and II, however, the reaction of III with amines afforded 3-amino-1-substituted thio-3-hydroxy-2-oxo-indoles (X), with no formation of any sulfenamides anticipated.
合成了新化合物 N-(取代硫)异恶唑(III),并对与几种核外基团的反应进行了研究,以与使用 N-(取代硫)邻苯二甲酰亚胺(I)和 N-(取代硫)琥珀酰亚胺(II)的反应进行比较:I、II 和 III 均与有机金属化合物、氰离子和三氯甲基碳负离子反应,分别生成硫化物(IV)、硫氰酸盐(V)和三氯甲基硫化物(VI)。然而,与 I 和 II 不同,III 与胺发生反应,生成 3-氨基-1-取代硫-3-羟基-2-氧代喹啉(X),未观察到任何预期的亚硫酰胺形成。
