(Germany). CODEN: GWXXBX. CLASS: IC: C07D207-456. APPLICATION: DE 83-3321157 11 Jun 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 27 N-Hydrocarbylmaleimides or their halogen, alkyl, or aryl derivs., potentially useful as monomers, are prepd. by heating the corresponding anhydrides and amines in H2O-immiscible solvents in the presence of acids with water distn. Thus, adding 93 g PhNH2 [62-53-3] over 30-90 min to 98 g maleic anhydride [108-31-6] in 150 mL refluxing xylene contg. 2.5% (based on reactants) H3PO4 with water distn. and heating 30 min more gave N-phenylmaleimide [941-69-5] in 92% yield.
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. .
