从2-氯-3-甲酰基喹啉1开始,使用不同的方法合成了新型吡唑并[3,4- b ]喹啉α-酮膦酸和羟基亚甲基双膦酸化合物。获得了新的膦酸化合物,以N-1衍生物的形式带有侧链带有1或3(n = 1或3)个亚甲基的侧链。使用NMR技术以及红外和高分辨率质谱,对所有膦酸化合物及其相应的酯和羧酸前体进行了充分表征,并通过光谱数据阐明了它们的结构。在此过程中,以获得具有两个亚甲基基团的N-1取代的衍生物(Ñ= 2)在侧链中,观察到意外的加成-环化级联反应,包括芳环的膦酰化和形成新的六元内酰胺环以提供四环系统。这是出乎意料的结果,因为在相似的实验条件下,已经制备的其他吡唑并[3,4- b ]喹啉衍生物和所有相应的吡唑并[3,4- b ]吡啶衍生物均未进行该反应。这种多米诺骨牌反应是通过不同的亚磷酸酯试剂发生的,但仅产生六元环。光谱数据允许鉴定新合成的四环化合物,并且化合物11的X射线衍射数据能够确认所提出的结构。

and baker’s yeast catalyzed, efficient synthetic routes have been first time developed for multicomponent cyclocondensations leading to bioactive tetrahydrobenzo[a]xanthene-11-ones (4a–h) and pyrazolo[3,4-b]quinolines (7a–i). The developed protocols are conducted at roomtemperature and gave better to excellent yields of the titled compounds. The biocatalytical resource, activated baker’s yeast is readily

rboxaldehyde and 1,3‐diphenylpyrazole‐4‐carbaldehyde were condensed with thiocarbohydrazide and malonic acid hydrazide derivatives. The condensation products obtained were converted into pyrazolidinoquinoline, pyrazoloquinoline, pyrrazolyl tetrazine, and thiazolidinone derivatives. The structures of all the products obtained were elucidated from their analytical and spectral data.

Novel tetraethyl ethylene-1,1-bisphosphonate esters derived from 1H-indazole, 1H-pyrazolo[3,4-b]pyridine, and 1H-pyrazolo[3,4-b]quinoline were synthesized by a Michael addition reaction of tetraethyl ethylidene-1,1-bisphosphonate with the corresponding heterocycle, using conventional heating and microwave-assisted methods. The microwave-assisted method provides shorter reaction times and better yields
