Abstract

Chloropyranodioxins (I) prepared by the reaction of malonyl chloride with mixed ketone were converted into 7-
(phenylamino)-pyranodioxins (II) which underwent the phenoxide rearrangement to yield the corresponding
pyridinodioxins (III), whose structures were determined by chemical conversions and spectroscopic studies.
