A two step synthetic strategy for obtaining 2-alkenyl-1,3-dicarbonyl compounds from the corresponding 1,3-dicarbonyl compounds is reported. The method is based on a Knoevenagel condensation and a Michael addition using a high order organocuprate procedure, and proves to be of general value, Obtained compounds are useful starting materials for the synthesis of furan derivatives, (C) 2002 Elsevier Science Ltd.
