PROCESS FOR THE PREPARATION OF TRANS-2,3-DISUBSTITUTED NAPHTHOQUINONES |
| 摘要 |
The invention concerns a process for the preparation of naphthoquinones of formula (I), in particular 2,3-disubstituted 1,4-naphthoquinones, in the trans configuration, which comprises reacting a compound in cis form or as a cis/trans mixture, with concentrated sulphuric acid at a temperature below +20°C. This process allows higher yields to be obtained. (see above formula) |
