Studies on dehydro-L-ascorbic acid arylosazones. Part II. Conversion into substituted azo-pyrazolones

Abstract
N.m.r. and i.r. spectroscopy, acetylation, benzoylation, and oxidation with periodate confirmed that the rearrangement product of dehydro-L-ascorbic acid phenylosazone is 1-phenyl-4-phenylazo-3-(L-threo-1,2,3-trihydroxypropyl)pyrazolin-5-one. A number of p-substituted derivatives of this compound and their acylation products have also been prepared.
