A versatile and highly stereoselective borylative cyclization to generate polyfunctionalized γ-lactams has been developed. The stereoselective synthesis of these key ring systems is crucial due to their ubiquity in natural products. We report the diastero- and enantioselective construction of di- and trisubstituted γ-lactam cores, with examples containing an enantioenriched quaternary carbon.

3,4-Dihydro-1,3,2-oxazaphosphorin-2-oxides (4a-r) have been prepared by the interaction of aryl β-aryl/alkylaminoethyl ketones (3a-r) with POCl3/Et3N.Various reactions of these compounds, which represent a new ring system, are reported.Few of these compou

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.
