A novel generation of oxazoleylide and interception with sulfonamide have been well developed to construct fully substituted amidines. This copper‐catalyzed four‐component reaction incorporates twodiazomolecules to target amidines and shows broad substrate scope, excellent functional groups tolerance and good to excellent yields.

A general procedure was developed for the annelation of a butenolide to an aromatic ketone that highlighted a manganese(III) oxidation of aromatic ketones. The oxidation of aromatic ketones with manganese(III) acetate in the presence of 2-bromoacetic acid or the Mn(II) salt of this carboxylic acid provided a regioselectively convenient synthesis of 2-(2-bromoacetoxy) ketones.
