Dewar benzenes have been subjected to detailed structural analysis using electron diffraction, 1 microwave spectroscopy, 2 Raman spectroscopy,3 photoelectron spectro-4 5 scopy, and theoretical calculation. The only X-ray analysis of a Dewar benzene has been performed on a chromium tetracarbonyl comp

In a preceding communication the hemi-acylal formation leading to a fixed chair-boat form 5 in bicyclo[3.3.l]nonanes has been discussed2). Aiming at a better understanding of this unusual phenomenon 31 two hydroxyketones capable of formation of the acetal derivative B were synthesized in which the e
Wodeshiol, a new lignan from Cleistanthus collinus, is shown to be 1, 5-dihydroxy-2e, 6e-dipiperonyl-3,7-dioxabicyclo[3,3, Oloctane, the first member of a new series of dihydroxy lignans. We have recently reported the isolation of a number of new lignans including arboreol (1 ), isoarboreol (2), and
