A Case of Competitive Demethylation by Boron Tribromide-methyl Sulfide Complex. A New Route to Oxazoloquinolines

A Case of Competitive Demethylation by Boron Tribromide-Methyl Sulfide Complex. A New Route to Oxazoloquinolines.-A one-pot synthesis of oxazoloquinolines (II) from substituted quinolines (I) by demethylation with boron tribromide-methyl sulfide is reported. The same way is used for the synthesis of (V). Steric hindrance by bulky R 1 or R 2 groups diminishes the yield.-(BEVIERE, C.; ROCHER, R.; CHENAULT, J.; Synth. Commun. 28 (1998) 6, 945-948; Lab.
