WHAT IS THE CORRECT STRUCTURE FOR PERIPLANONE A?

The stereostructures of periplanone A and its rearrangement product have been elucidated on the basis of molecular mechanics calculations together with 1H NMR spectral data.

Synthesis of (+-)-PA 22-VII, the racemate of the rearrangement product of Persoons's periplanone-A

A synthesis of the racemate of 5 was achieved to prove its identity with PA 22-VII, the stable and biologically inactive rearrangement product of Persoons's periplanone-A.

SYNTHETIC CONFIRMATION OF THE STRUCTURE OF THE REARRANGEMENT PRODUCT OF PERIPLANONE-A

The stable and biologically inactive rearrangement product of Persoons's periplanone-A was shown to be 12 by the synthesis of (+/-)-12

CLARIFICATION OF THE STRUCTURE OF PERSOONS'S PERIPLANONE-A, AN ARTIFACT DERIVED FROM HAUPTMANN'S PERIPLANONE-A

Thermal rearrangement of Hauptmann's periplanone-A by GLC gave Persoons's periplanone-A, of which structure was determined through an X-ray crystallographic analysis of the corresponding alcohol.
