摘要

Svn (or anti) cinnamaldehydeoxime (la,b) undergoes Diels-Alder addition to tetrabromo-p-benzoquinone (2) in dry xylene in 1 :1 and 2 :1 molar ratios to give the mono- and diadducts 3 and 4a,b respectively.The reaction of 3 with thioamides in ethanol gave thiazoloquinoline diones 6a-d,whereas with acid amides in ethylene glycol,it gave oxazoloquinolinediones
