The three dimensional structure of all-cis-diepoxy[15]annulenone and some implications from the structure
Abstract
An X-ray structural analysis of all-cis-diepoxy[15]annulenone (1) revealed that (1) exists in two different conformations, each of which possesses a saucer-like three-dimensional geometry, like that of the polyaromatic 14π hydrocarbon corannulene (5).
