The new 5H‐thiazolo[4,3‐b]quinazoline‐3,5(1H)‐diones 3, 4a–c, 5a–c and 5H‐thiazolo[2,3‐b]quinazoline‐3,5(2H)‐diones 9a–c, 11a–c were prepared by reaction of anthranilic acid with the 2‐thiazolidinone‐4‐thione derivatives 1b, 6a–c, 7a–c and the 5‐substituted 2‐(alkylmercapto)‐2‐thiazolin‐4‐ones 8a‐c, 10a‐c, respectively.
新的 5H-thiazolo [4,3-b] quinazoline-3,5 (1H) -diones 3, 4a-c, 5a-c 和 5H-thiazolo [2,3-b] quinazoline-3,5 (2H) -Diones 9a - c, 11a - c 是通过邻氨基苯甲酸与 2-噻唑烷酮 - 4- 硫酮衍生物 1b, 6a - c, 7a - c 和 5 - 取代的 2- (烷基巯基) -2 - 噻唑啉 4 反应制备的-ones 8a-c, 10a-c,分别。
