Syntheses ofs-Triazine Derivatives from Uronic and Polyuronic Acids

Determination of Uronic Acids in Cellulosic Materials

Methods for the determination of uronic acids, based on the estimation of the amount of carbon dioxide evolved by these acids in a given length of time during treatment with a boiling solution of hydrochloric acid, were found to fail when cellulose or other carbohydrate material was present, since these substances also decomposed with the evolution of some carbon dioxide. An investigation of th...

Oxidative Degradation Of Triazine Derivatives

Syntheses of Anisomycin Derivatives

The structure of anisomycin has been determined by X-ray investigation4 and the absolute configuration was confirmed by chemical correlation.5 Anisomycin has attracted considerable synthetic interest, and several synthetic studies, derivative syntheses as well as total syntheses, have been reported.6 Especially, the synthesis of its analogues has revealed the structure-activity relationship of ...
