Synthesis and structure of 1H-4-amino-2-oxoquinoline-3-carboxylic acid esters: Synthesis and structure of 1H-4-amino-2-oxoquinoline-3-carboxylic acid esters.Several substances are used for example 1769-24-0 and 99429-64-8 which are their cas registry numbers. Ukrainets, I. V.; Bezuglyi, P. A.; Nikola, Skaif; Gorokhova, O. V.; Sidorenko, L. V. (Nats. Farm. Univ., Kharkov 61002, Ukraine). Zhurnal Organichnoi ta Farmatsevtichnoi Khimii, 2(1), 39-44 (Russian) 2004 Natsional'nii Farmatsevtichnii Universitet. CODEN: ZOFKAM. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 75 Two approaches to the synthesis of 1H-4-amino-2-oxoquinoline-3-carboxylic acid esters I (R = Me, Et) are discussed. NMR spectroscopy studies and X-ray diffraction anal. established that these esters exist in DMSO-d6 soln. and in the solid state exclusively as 4-amino-2-oxo tautomers shown. .

Syntheses of some 4-anilinoquinazoline derivatives: Rocco, Silvana A.; Barbarini, Jose Eduardo; Rittner, Roberto (Physical Organic Chemistry Laboratory, Instituto de Quimica, UNICAMP, Campinas 13084-971, Brazil). Synthesis, (3), 429-435 (English) 2004 Georg Thieme Verlag. CODEN: SYNTBF. ISSN: 0039-7881. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Some 6,7-dimethoxy-N-phenyl-4-quinazolinamine derivs. and the corresponding unsubstituted compds. were synthesized from 2-amino-4,5-dimethoxybenzoic acid and the appropriate substituted anilines. Other related quinazolines or their synthetic intermediates were also obtained. A large no. of the described quinazolines are new compds., while the remaining were prepd. 1769-24-0 which is the cas registry number is also used here. by a more efficient procedure. The main goal for the synthesis of these compds. comes from the fact that the 4-anilinoquinazoline pharmacophore is an important unit, which is found among the ATP-competitive inhibitors of several protein kinase enzymes. The biol. 1769-24-0 is the cas registry number of certain chemical which is used as reagents here. activity of the compds. thus prepd. was not reported. ..
