| titleOfInvention | Preparation of rifamycin derivative |
| abstract | PURPOSE: To prepare 3-iminomethyl derivative of rifamycin SV, easily, in high yield, by the two stage reaction from rifamycin B or O via 3-iminomethyl derivative of rifamycin S. n CONSTITUTION: Rifamycin B or rifamycin O is converted to 3-iminomethyl derivative of rifamycin S of formula I (R is alkyl) by reacting with HCHO and a primary amine or with an aldiimino derivative of HCHO and a primary amine, in the presence of an oxidizing agent. The reaction product (1 mole) is further made to react with (substituted-)hydrazine (≥2 moles) to afford the objective 3-iminomethyl derivative of rifamycin SV of formula II (R' is hydrozono, substituted hydrazono). n COPYRIGHT: (C)1979,JPO&Japio |
