Thiazolo[5,4-c]isoquinoline (I) has been synthesized by cyclization of 4-amino-3-thiocyano-isoquinoline (IX) to 2-aminothiazolo[5,4-c]isoquinoline (X), which was converted into I via the 2-chloro derivative XI. Some 2-substituted derivatives of I were obtained by displacement of the chlorine atom in XI. The attempted preparation of 3-chloro-4-nitroisoquinoline as an intermediate in the synthesis of
噻唑并 [5,4-c] 异喹啉 (I) 已通过 4-氨基-3-硫氰基-异喹啉 (IX) 环化为 2-氨基噻唑并 [5,4-c] 异喹啉 (X) 合成,后者被转化为I 通过 2-氯衍生物 XI。通过置换XI中的氯原子得到I的一些2-取代衍生物。尝试制备 3-氯-4-硝基异喹啉作为合成 I 的中间体未成功。研究了I及其衍生物的核磁共振和紫外光谱。
