title: Total asymmetric synthesis of the aphidicolin derivative (11R)-(-)-8-epi-11-hydroxyaphidicolin using tandem transannular Diels-Alder/aldol reactions.
abstract: [reaction: see text] Aphidicolin unnatural derivative (2) was synthesized using a new tandem transannular Diels-Alder/aldol methodology. The 8-epi-aphidicolane skeleton is constructed in a highly diastereoselective manner and converted into (11R)-(-)-8-epi-11-hydroxyaphidicolin (2). An efficient method for the difficult C16 funtionalization is presented.
