A concise synthesis of the oxygen substituted ring A compound 2 found in Taxol®1a and Taxotere®1b starting from 2,2-dimethylcyclohexane-1,3-dione and proceeding via the key intermediates 8 and 11, is described. The absolute configuration of 2 was established from an X-ray crystal structure determination of a 4-bromophenylbenzoate derivative, viz. 15.
