英文摘要 | A simple synthesis of 3-amino-6/8-substituted-1h-pyrazolo[4,3-c]quinolines via closed ring reaction of 4-amino-3-aryl-5 mercapto-s-1, 2, 4-triazoles with 1, 4-dihydro-4-oxo-quinoline-3-carboxylic acids in the presence of phosphoryl chloride, followed by the ring-opening reaction in the presence of hydrazine hydrate was described. this novel and straightforward method for the construction the 3-arnino-1h-pyrazolo[4,3-c]quinolines can be carried out under mild conditions by using readily accessible or commercially available inexpensive materials. the new compounds were dertemined by elementary analyses, ir, h-1 nmr and ms spectra. their spectral properities were also discussed. this mothod may represent a potentially useful route to otherwise laboriously accessible condensed pyrazoles, ring systems. with the advantage of economy, a single pot procedure, excellent yields and mild conditions. this condensed pyrazoles can be synthesized on a large scale conveniently and economically. |
