Abstract
The regioselective enolization of 4-substituted cyclopentene-1,3-dione s 3a-e is investigated under basic and acidic conditions. Enols 1 and enolethers 6, 7 are formed with the simultaneous endocyclic double bon d migration in the side chain. (C) 1998 Elsevier Science Ltd. All righ ts reserved.
