The cationic Ru–H complex [(C6H6)(PCy3)(CO)RuH]+BF4– (1) with 3,4,5,6-tetrachloro-1,2-benzoquinone (L1) was found to be a highly effective catalyst for the deaminative coupling reaction of 2′-hydroxyaryl ketones with simple amines to form 3-substituted flavanone products. The analogous deaminative coupling reaction of 2-aminobenzamides with branched amines directly formed 3,3-disubstituted quinazolinone products. The catalytic method efficiently installs synthetically useful flavanone and quinazolinone core structures without employing any reactive reagents.

Certain spirocyclic heterocyclic compounds, and their pharmaceutically-acceptable salts, are inhibitors of the aldose reductase enzyme, and so are useful for the control of diabetic complications. Exemplary compounds include compounds of the formula where
