摘要
The total synthesis of the title compound has been accomplished in 20 steps. The key step is a free radical cyclization of vinyl bromide 29 to afford 30. The synthesis also features an efficient Diels-Alder reaction of 2,3-dimethylmaleic anhydride with 1-(tert-butyldimethylsiloxy)-butadiene. The oxetane moiety of merrilactone A is fashioned via a Payne-like rearrangement of a hydroxyepoxide (see 2 → 1). Copyright © 2002 American Chemical Society.
