bearing an o-ester group were converted to thiourea derivatives 2a-c, 6a-b, and 10a-b, respectively, using β-aminoalcohols, and to the fused ring systems, e.g., thieno[3,2-d]pyrimidine 4a-b, pyrido[2,3-d]pyrimidine 8, pteridine 11a, thiazolo[3,2-a]pyrido[2,3-d]pyrimidine 7a-b, and thiazolo[3,2-a]mieno[3,2-d]pyrirnidine 3a-c, derivatives.
杂环异硫氰酸酯1,5,9,轴承的直径: -酯基团转化为硫脲衍生物2A-C,图6a-b ,和图10A-B ,分别使用β氨基醇,以及稠环体系,例如,噻吩并[3,2-d]嘧啶4a-b,吡啶并[2,3- d ]嘧啶8,蝶啶11a,噻唑并[3,2- a ]吡啶并[2,3 - d ]嘧啶7a-b和噻唑并[ 3,2- a ] mieno [3,2 - d ]吡啶3a-c衍生物。
