SYNTHESIS AND DETERMINATION OF THE LIPOTROPIC ACTIVITY OF THE BETAINE HYDROCHLORIDES OF dl-SERINE, GTHREONINE, AND dl-ALLOTHREONINE*
This paper reports the synthesis of the betaine hydrochlorides of serine, threonine, and allothreonine and a study of the action of these substances on the lipid content of the livers of rats fed a high fat, low protein diet. This work was undertaken for two purposes. Best and Huntsman (1) found that choline prevented the development of fatty livers in rats fed a high fat diet and that betaine ...

متن کاملAHIM ACIDS; 13'. INVESTIGATIONS ON THE SYNTHESIS OF DL-SERINE FRUH a-HALDACRYLIC ACID DERIVATIVES FRANZ EFFENBERGER* and CERHARD ZOLLER'
The alkoxide-catalyzed addition of alcohols 2 to a-chloroacrylonitrile (1) at -35°C gives rise to 3-alkoxy-2-chloropropancnitriles 3; at D-5°C with excess _2 alkyl 3-alkoxy-2-chloropropanicidates 3 are obtained. The yields of 3 or 4 decrease with increasing pK, values of the alcohols 2. In the basecatalyzed addition of phenols 5 to 1, a temperature-dependent addition equilibrium is set up in wh...
متن کاملSYNTHESIS OF a-AMINO-p-HYDROXY-n-BUTYRIC ACIDS VII. AN IMPROVED SYNTHESIS OF DL-ALLOTHREONINE
Several methods are available for the synthesis of DL-threonine (l-3). However, each of these involves the separation of threonine from a mixture containing varying proportions of the isomeric allothreonine. Recently it has been reported that derivatives of rm-allothreonine may be converted to DL-threonine in excellent yields (3-5). These developments make the preparation of nn-allothreonine of...
