Aryl β-arylaminoethyl ketones (1), when reacted with phosphorus oxychloride followed by treatment with triethylamine, afford 3,6-diaryl-2-chloro-3,4-dihydro-1,3,2-oxazaphosphorin-2-oxides (3a-u), a hitherto unreported ring system.The oxazaphosphorin (3q), viz. 2-chloro-3-m-anisyl-6-phenyl-3,4-dihydro-1,3,2-oxazaphosphorin, is converted into 7-methoxy-4-phenylquinoline on keeping.This transformation is specific to 3q since other oxazaphosphorins fail to give the quinoline derivative.
