New Isomerism of Halogeno-hydroxy-benzoyl-toluic Acids. VII

Selective Oxidation of Xylenes to Toluic Acids

A mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. Reactions are clean and catalysts can be recovered easily and reused.

SYNTHESIS 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...

New Long-chain Hydroxy Acids from Grevillea decora

In addition to the w-5 olefinic acids found in other Grevillea species, about 10% ?f the acyl groups of G. decOI'a seed oil contain a hydroxy group and an w-5 double bond. Th: chamlengths of these acids are from C22 to C30 , with the largest concentration at the C26 and C28 chamle.ngths. ~le hydroxy group is located on odd carbons from carbon-5 through carbon-l3. These a~lds prevIously .were ~n...
