  • Synthesis of carboxylic acid glucuronides
    Patent number: 5633357
    Abstract: A method of producing a carboxylic acid glucuronide by reacting a carboxylic acid precursor with a blocked sugar epoxide precursor is disclosed. Also disclosed are: deuterated 11-nor-.DELTA..sup.8 - or .DELTA..sup.9 -THC carboxylic acid glucuronide having a deuterated hydrocarbon chain; 5'-deuterated 11-nor-.DELTA..sup.8 - or .DELTA..sup.9 -THC-carboxylic acid or 5'-deuterated .DELTA..sup.8 - or .DELTA..sup.9 -THC glucuronide. The compositions are useful as GC-MS standards; in methods for preparing antibodies reactive with a THC glucuronide; and, in GC-MS diagnostic methods for THC metabolites.
