We report a set of electrochemically regulated protocols for the divergent synthesis of ketones and β-keto esters from the same β-hydroxycarboxylic acid starting materials. Enabled by electrochemical control, the anodic oxidation of carboxylic acids proceeded in either a one-electron or a two-electron pathway, leading to a 1,4-aryl transfer or a semipinacol-type 1,2-group transfer product with excellent

Condensation of diphenylacetalclehydes and 1,1-diphenylacetones with malonodinitrile and cyclization of obtained aryl-ylidenemalonodinitriles in concentrated sulfuric acid leads to 1-amino-4-arylnaphthalene-2-carbonitriles. The benzannulation reaction is accompanied by a quasi-aromatic rearrangement. Preliminary tests of some synthesized aminonitriles have revealed their considerable biological activity against phytopathogenic fungi. (c) 2008 Elsevier Ltd. All rights reserved.
