Abstract
The behavior of 1-R-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid pyridinylmethylene- hydrazides under bromination conditions using molecular bromine has been studied. It has been found that the 1- N -allyl derivative is characteristically halocyclized to the corresponding oxazolo[3,2- a ]quinoline, whereas the 1- N -hexylsubstituted acylhydrazone is unexpectedly brominated in the azomethine fragment.
