Abstract


A series of regioisomeric ketene-O,O-dialkyl acetals were prepared from ambident ?-dicarbonylfuroindoles by trapping the enol tautomers of esters and lactones with diazomethane. Definitive structural characterization was accomplished by X-ray crystal structure determination on a ketene-O,O-dimethyl acetal (R = Me).
