The First Enantiocontrolled Synthesis of Naturally Occurring Polyoxygenated Cyclohexenylmethanol Dibenzoates (-)-Zeylenol, (-)-Uvarigranol G, (-)-Tonkinenin A and (+)-Pipoxide.

The first enanticontrolled synthesis of five naturally occurring polyoxygenated cyclohexenylmethanol dibenzoates has been achieved to confirm three [(–)-zeylenol, (–)-uvarigranol G, (+)-pipoxide], revise one [(–)-tonkinenin A] and disprove one [(–)-epizeylenol] of the proposed structures.
