Abstract 3-Aryl-2-bromopropanoic acid esters reacted with o-phenylenediamine, 2-sulfanylaniline, and L-cysteine to give quinoxaline, 1,4-thiazine, and thiomorpholine derivatives, respectively, containing an arylmethyl substituent. Analogous 1,4-benzoxazine derivatives were synthesized by reactions of 3-aryl-2-bromopropanoyl chlorides with 2-aminophenol or 2-methoxyaniline.
摘要 3-芳基-2-溴丙酸酯与邻苯二胺,2-硫烷基苯胺和L-半胱氨酸反应,分别得到包含芳基甲基取代基的喹喔啉,1,4-噻嗪和硫代吗啉衍生物。通过3-芳基-2-溴丙酰氯与2-氨基苯酚或2-甲氧基苯胺的反应合成类似的1,4-苯并恶嗪衍生物。
