C. Beviere et al., A CASE OF COMPETITIVE DEMETHYLATION BY BORON TRIBROMIDE METHYL SULFIDE COMPLEX - A NEW ROUTE TO OXAZOLOQUINOLINES, Synthetic communications, 28(6), 1998, pp. 945-948
Reaction of boron tribromide-methyl sulfide complex with 6-methoxy-5-a
midoquinolines provides oxazolo(4,5-f) quinolines. In contrast under s
imilar conditions boron tribromide gives only 6-hydroxy-5-amidoquinoli
nes.
