3-(2-Aryl-2,3-dihydro-benzo[b][1,4]thiazepin-4-yl)chromen-2-ones (2a, e, f) and (Z)-3-(2,3-dihydro-2-arylbenzo[b][1,4]thiazepin-4(5H)-ylidene)chroman-2-ones (3a-f) have been synthesized by the reaction of 3-aryl-1-(3-coumarinyl)propen-1-ones (1a-f) with 2-aminothiophenol in a hot mixture of toluene and acetic acid. Structures of all new compounds and their complete 1H and 13C assignments were achieved
3-(2-Aryl-2,3-dihydro-benzo [ b ] [1,4] thiazepin-4-yl)chromen-2-ones(2a,e,f)and(Z)-3-(2,通过3-芳基-1-(3)的反应,合成了3-二氢-2-芳基苯并[ b ] [1,4]噻唑啉-4(5 H)-亚烷基)苯并二氢吡喃-2-酮(3a-f)。 -香豆素基)丙烯-1-酮(1a-f)与2-氨基硫代苯酚在甲苯和乙酸的热混合物中。所有新化合物的结构及其完整的1 H和13 C赋值是通过将不同的一维和二维nmr实验与各种光谱技术结合使用而获得的。
