โœฆ Synopsis


Among the known antitumor compounds, a unique structural feature is the Spiro ring system of fredericamycin A (1j.l Recently, Rama Rao et al. prepared the model spiro(4,4) nonane Z2 from a 2-aryl 1,3-indanedione.3

The report of that conversion prompts our communication of an alternative approach to joining the two perpendicular moieties of fredericamycin; our strategy led to the construction of the frederieamycin model 3.

This paper describes, for the first time, a short synthetic procedure for [2,2%-bi-1H-indene]-3,3%-dialkyl-3,3%-dihydroxy-1,1%-diones (1a-f). The key feature of this synthetic method lies in the participation of oxygen when the intermediate arises from the nucleophilic addition of alkylmagnesium bro
