A very simple strategy for the construction of 2,3-benzofused 8-oxabicyclo[3.2.1]octane derivatives is reported. This new process is based on a platinum-catalyzed tandem intramolecular hydroalkoxylation-hydroarylation reaction of aryl-substituted pentynol derivatives. This reaction has been applied in the key step of the total synthesis of bruguierol A, allowing the synthesis of this natural product in a very straightforward manner.

Total synthesis of natural product (±)-bruguierol A was accomplished in 10-steps and with an overall 16.8% yield. The embedded unique 8-oxabicyclo[3.2.1]octane core skeleton in this natural product was constructed via a novel Sc(OTf)3-catalyzed intramolecular [3+2] cycloaddition of cyclopropane, which was developed recently in this laboratory. This general synthetic strategy can be potentially applied
