| titleOfInvention | Process for producing etoposide compounds |
| abstract | The ratio of the protected 4'-demethyl-4-epipodophyllotoxin and the protected glucose derivative in an amount of 0.1 to 7 times by volume relative to 1 part by weight of the protected 4'-demethyl-4-epipodophyllotoxin The reaction is carried out in a (non) halogen-type organic solvent to prepare an etoposide derivative of the formula (3) in which the terminal group is protected, and then these protecting groups are removed as necessary.n n n n n n n n (Wherein R 1 and R 2 are each a protecting group of hydroxy)n n n By using a non-halogen type organic solvent in place of the harmful halogen solvent, it is possible to minimize the generation of unnecessary by-products, so that etoposide can be produced in high purity and high yield. |
