The synthesis and chemistry of azolenines
The synthesis and chemistry of azolenines. Part 2. A general synthesis of pyrrole-2-carboxylic acid derivatives by the reaction of 2H-azirines with enamines, and the crystal and molecular structure of ethyl 3-phenyl-4,5,6,7-tetrahydroindole-2-carboxylate. Law, Kam Wah; Lai, Ting Fong; Sammes, Michael P.; Katritzky, Alan R.; Mak, Thomas C. W. (Dep. Chem., Univ. Hong Kong, Hong Kong, Hong Kong). J. Chem. Soc., Perkin Trans. 1, (1), 111-18 (English) 1984. CODEN: JCPRB4. ISSN: 0300-922X. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Section cross-reference(s): 75 1H-Pyrrole-2-carboxylic acid derivs. were prepd. by reaction of substituted 2H-azirines with enamines followed by acid treatment of the resulting dihydropyrroles. E.g., treatment of azirine I with the enamine II at 25° followed by treatment of the resulting 1:1 adduct with anhyd. HCl/MeOH at 0° gave 84% of the pyrrolecarboxylate III.In this experiment, several chemicals are used like 89649-68-3 and 89649-09-2 The structure of III was established by x-ray anal.: the mols. pack in highly coplanar, centrosym., H-bonded pairs. .
Preparation of pyrrole-2-carboxylic acid
Preparation of pyrrole-2-carboxylic acid. Cho, Shuren; Mizuno, Akira (Suntory, Ltd., Japan). 634-97-9 and 109-97-7 are also occured in this study. Jpn. Kokai Tokkyo Koho JP 04018068 A2 22 Jan 1992 Heisei, 3 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C07D207-34. APPLICATION: JP 90-119994 11 May 1990. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) The title compd. (I) is prepd. by treatment of pyrrole with COCl2, followed by hydrolysis. A soln. of pyrrole and PhNMe2 in PhMe was treated with a soln. of ClCO2CCl3 in PhMe at 0°, stirred at room temp. for 18 h, refluxed for 2 h, then treated with aq. NaOH at 0° to give 67% I. .
