• This compound has been already synthesized by Nozaki 3b. However the problem lies in the preparation of 3-bromo -2,2,5,5-tetramethylcyclohexa-l,3-dione 5which we were unable to perform selectively under various experimental conditions. Under the conditions cited by Nozaki 3b (ref. to Stetter's work) and using NBS, the bromination is very slow and provides a mixture of products from which the desired pure product 5. can be isolated in low yield by crystallization, (b) Okada T., Kamogawa K., Kawanisi M. and Nozaki H., Bull.
