A convenient synthesis of dibenzo[a,c]cyclooctene based on thioenol ether reduction

9,10,11,12-Tetrahydrodibenzo[a,b]cyclooctane-9,12-diol (6) is found to be reluctant to double bond forming elimination. It gives a bridge ether (7) instead. The corresponding diketone (5) reacts with benzyl mercaptan to provide the bis-thioenol ether (8-a

BARRIERS TO RING INVERSION IN DIBENZOCYCLOOCTENE AND ITS DIHYDRO AND TETRAHYDRO DERIVATIVES BY RACEMIZATION AND NMR BANDSHAPE STUDIES

Dibenzocyclooctene and its 9,10-dihydro and 9,10,11,12-tetrahydro derivatives have been resolved by chromatography and their inversion barriers determined by thermal racemization.The 9,12-dihydro derivative has been studied by 1H NMR bandshape technique.
