A direct synthesis of carbaldehydes through intramolecular dehydrogenative aminooxygenation has been developed. The process uses a catalytic amount of copper(II) in DMF or DMA under oxygen and does not require additional oxidants (see scheme). Mechanistic studies suggest that the carbonyl oxygen atom of the aldehyde is derived from oxygen through a copper-mediated oxygen activation process via a peroxy-copper(III) intermediate. Copyright

A method for the synthesis of oxymethyl dihydropyrroles (pyrrolines) and dihydroimidazoles has been developed via Cu(II)-mediated intramolecular aminooxygenation of alkenylimines and alkenylamidines, respectively, with 2,2,6,6-tetramethyl-1-piperidinyloxy radical (TEMPO).
