| titleOfInvention | The preparation method of 2,3-bis-substituted quinoxaline derivative |
| abstract | The invention discloses a kind of novel processing step of 2,3-bis-substituted quinoxaline derivative.With arylamine and 1,3-dicarbapentaborane-2-oxime compounds is after raw material carries out condensation, the electrophilic substitution reaction of nitrogen positive ion in molecule is utilized to carry out cyclisation, dexterously " condensation-cyclisation " reaction is connected, two step one still process operations obtain 2,3-bis-substituted quinoxaline derivatives phenyl ring with different substituents.Compared with prior synthesizing method, the method cheaper starting materials is easy to get, without the need to processing intermediate product in process, simplify synthesis step, particularly there is multiple replacement mode in aromatic amine compounds on phenyl ring, achieve the variation of product structure, be conducive to the further investigation to quinoxaline derivatives.Utilize method of the present invention have also obtained new compound that 18 have no report. |
