METHOD OF THN APPLICABLE 3-O-PROCESSED MORPHINones AND CARBOXYLIC DIANOL 3-O-PROCESSED MORPHIN FISH

摘要

Methods by preparation of aldehydes and ketones are revealed,which contain (allow) the corresponding primary or secondary alcohol to react in the presence of trichloroisocyanic acid,compound of type R1SR2 and base. In a sense,Alcohol is a compound of the type (I) in which R3 is a protective agent. Methods for the preparation of 3-O-protected morphine diphenyl carboxylate salts are also revealed,Incorporating a type (I) compound to oxidise the presence of a content-chlorine compound and a type R1SR2 compound and a release of the grade product oxidation to react after an acidification factor.
