6-氯-2,3,4,9-四氢-1H-咔唑-1-酮 | 6-chloro-2,3,4,9-tetrahydro-1H-carbazol-1-one | 14192-67-7 | C12H10ClNO | 219.671 |
1-Hydroxyimino-1,2,3,4-tetrahydrocarbazoles (1) were reduced with zinc in acetic acid and acetic anhydride and with bakers’ yeast in an aim to synthesize 1-aminocarbazoles, but interestingly the reaction gave hitherto unknown compounds, 2-acetoxy-1-(acetylamino)carbazoles (2) and 6- [acetoxy(hydroxy)methyl]-1-hydroxylaminocarbazoles (3), respectively. A plausible mechanism for the formation of compounds 2 and 3 is proposed. All new compounds were characterised by IR, NMR, mass spectral methods and elemental analysis.
