Abstract

Addition of NaOMe, NaOEt, or NaOPr(i) to dispironaphthalenone 1 resulted in the formation of diketones 4a-c and 5a-c. The structure assigned to 4a was confirmed by conversion to the known hemiacetal 3. Similar addition of carbon nucleophiles like diethyl malonate, dimethyl malonate, methyl cyanoacetate, and ethyl cyanoacetate afforded diketones 4d-g. Formation of these compounds has been rationalized.
