A facile and efficient protocol for rhodium-catalyzed amination of quinoline N-oxides at the C-8 position using simple and commercially available trifluoroacetamide as the amino source has been developed, which proceeds with perfect regioselectivity at room temperature and short reaction times. This catalytic system is highly convenient on a gram scale. The desired products feature diverse functional

The invention relates to a method for combatting dandruff and anti-dandruff shampoos containing compounds having the structural formula in tautomeric form: ##SPC1## And metal salts and complexes thereof wherein R.sub.1 and R.sub.2 are hydrogen, alkyl, cycloalkyl, aryl, alkylthio, halogen, nitro, trifluoromethyl or alkoxy; x is an integer from 1 to 4 and y is an integer from 1 to 2.
Provided herein are heterocyclic derivative compounds and pharmaceutical compositions comprising said compounds that are useful for inhibiting plasma kallikrein. Furthermore, the subject compounds and compositions are useful for the treatment of diseases wherein the inhibition of plasma kallikrein inhibition has been implicated, such as angioedema and the like.
