title: Total synthesis of (+)-dibromophakellin and (+)-dibromophakellstatin.
abstract: A new method for the preparation of quaternary chiral aminals has been developed that employs an enamide-type Overman rearrangement process. This methodology was applied to enantioselective total syntheses of (+)-dibromophakellin and (+)-dibromophakellstatin.
