چکیده

A three-component reaction forming dihydro 2,7-naphthyridine-1-ones has been developed. These unstable dihydro intermediates can be either oxidized or reduced to form naphthyridones or tetrahydro naphthyridones, respectively. The reaction tolerates a large variety of aldehydes and amines, and the produced compounds are analogs of the natural product lophocladine A.
