Lewis acid-mediated reactions of 1-cyclopropyl-2-arylethanone derivatives with diethyl 2-oxomalonate and ethyl 2-oxoacetate
TMSOTf-mediated reactions of 2-aryl-1-(1-phenylcyclopropyl)ethanones 1 with diethyl 2-oxomalonate 2 afford a novel method for the synthesis of spiro-γ-lactone derivatives 3 in good to excellent yields via a sequential reaction involving a nucleophilic rin
