Novel Products from the Rearrangement of Some [n.3.1]Propellanes

The title compounds, (3aα,5α,6α)-4,4,6-trichloro-7-methoxy-3,4,5,6-tetrahydro-2H-3a,5-methanoazulene and (3aα,6α)-(E)-8,8-dichloro-5-chloromethylene-6-methoxy-1,2,3,4,5,6-hexahydrο-3a,6-methanο-3aH-indene, both C12H13C130, were formed by mild thermolyses of two related [4.3.1]propellanes and are of interest in the development of new methods for preparing novel analogues of the anti-cancer drug Taxol.
