| titleOfInvention | Method for preparing 4beta,-amino-4'-demethyl-4-desoxypodophyllotoxin |
| abstract | The invention relates to a method for synthesizing 4ss-amino-4'-demethyl-4-desoxypodophyllotoxin of formula (1), characterized by comprising the following successive steps: a) reacting, in a pure weak acid or in a mixture consisting of acid, water and of organic solvent, without another solvent, at a temperature higher than the ambient temperature, thiourea with 4ss-halogenoacetamido-4'-demethyl-4-desoxypodophyllotoxin, and; b) recovering the 4ss-amino-4'-demethyl-4-desoxypodophyllotoxin. |
