We accessed alcohol 9 in 4 steps from Maimone's enone (22, Figure ). First, conjugate addition of the cuprate derived from 3-furyl lithium provided ketone 23 as a single diastereomer. Then, β-elimination of the OTBS group and α-iodination provided known iodoenone 24. By using the -OTBS group to block one face of enone 20, we could reliably set the γ-stereocenter and later eliminate the blocking group to access enantiopure cyclopentenones in an efficient manner. Finally, diastereoselective 1,2reduction delivered the desired alcohol 9 to be used as a nucleophile in an etherification reaction.
