Abstract

Spiniferin-1, a rare planar chiral natural product with a 1,6-methano[10]annulene skeleton, has been synthesized via a novel polyfluoroalkanosulfonyl fluoride induced cascade carbocation rearrangement reaction. Natural spiniferin-1 was established as a racemic mixture by comparing its specific rotation with those of our synthesized Sp -(+)-spiniferin-1 and its Rp -(–)-enantiomer.
