Abstract
The silyl enol ether of alpha-diazoacetoacetate is used for the annela tion of aromatic oxo compounds. The method involves condensation with the oxo compound in the presence of TiCl4 followed by rhodium octanoat e-catalyzed ring closure to afford furan derivatives by direct carbene insertion and beta-naphthol esters by a Wolff rearrangement pathway.
