Novel benzologs or pyrazolo-quinazoline derivatives of the formula (I)
wherein X and Y are independently selected from oxygen, sulphur and imino and wherein ring (C) is a pyrazole ring fused to ring (B) via one of the three ortho-positions or sides of ring (B); the fused pyrazole ring (C) is either in the 4,3- or the 3,4-arrangement; and tautomers of formula (I) compounds; when X is not oxygen, i.e. stands for sulphur or imino, Y may stand for a covalent bond that links the hydrogen directly to the carbon atom in position 2.
式(I)的新型苯并类化合物或吡唑-喹唑啉衍生物
其中 X 和 Y 独立选自氧、硫和亚氨基,且环 (C) 是通过环 (B) 的三个正交位置或侧面之一与环 (B) 融合的吡唑环;融合的吡唑环 (C) 为 4,3- 或 3,4- 排列;以及式 (I) 化合物的同系物;当 X 不是氧,即代表硫或亚氨基时,Y 可代表将氢直接与碳相连的共价键。当 X 不是氧时,即代表硫或亚氨基时,Y 可代表将氢直接连接到第 2 位碳原子的共价键。
