Process For Producing Benzo[C]Phenanthridine Derivative |
| abstract |
A compound represented by the following formula (1): [wherein R1 and R2 each independently represents hydroxy, provided that R1 and R2 may be bonded to each other to form methylenedioxy, etc.; X represents halogeno; and R3 represents a protective is subjected to a cyclization reaction with the aid of an organic silyl hydride and then aromatized with an oxidizing agent to produce a benzo [c] phenanthridine derivative represented by the following formula (2): [wherein R1, R2, and R3 have the same meanings as defined above]. |
