The first enantiocontrolled synthesis of naturally occurring polyoxygenated cyclohexenylmethanol dibenzoates (–)-zeylenol, (–)-uvarigranol G, (–)-tonkinenin A and (+)-pipoxide

Abstract

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.
