摘要: This invention concerns a process for producing phenolic substances with beneficial biological activities in a high yield, which comprises: subjecting a glycose of which an OH group at the 1 position is substituted for a halogen atom and of which other groups are substituted for acyl groups, and a phenol of which at least one of the ortho-positions in regard to phenolic OH groups is substituted to reaction with an alkali metal hydride in dimethylsulfoxide or dimethylformamide in the presence of or non-presence of a quat-ammonium salt and then hydrolyzing said acyl groups with an alkaline substance.

摘要: An immunosuppressive agent which has low toxicity and which exhibits excellent effectiveness even if it is orally administered is presented. The immunosuppressive agent of the present invention is characterized in that it contains .delta.-opioid antagonist having high selectivity to .delta.-opioid receptor. The present invention also provides a process of producing a naltrindole derivative characterized by reacting naltrexone or a salt thereof with a phenylhydrazine derivative in a solvent in the presence of methanesulfonic acid.
