                                    A synthesis of modhephene has been achieved, the key feature of which is the use of a novel nucleophilic addition/rearrangement reaction to develop the carbon framework.  Stereochemical control of the stereogenic center bearing the methyl group was accomplished by variation of the hydrogenation conditions.  As a byproduct of this work, we have clarified structural assignments of intermediates from previous syntheses.
