Equilibration of the 7 alpha-->7 beta isomers of 7-substituted 6,14-ethenomorphinanes has been accomplished, for the first time, in dipolar aprotic solvents by the application of bases with weak nucleophilic character. Transformation of the 7 beta-nitrile with phenylmagnesium bromide led to a new type of 6,6 '-dimeric compound.

A series of 15,16-didehydro-compounds has been prepared by mercury(II) acetate dehydrogenation of 6,14-endo-ethenotetrahydro-thebaines and -oripavines. The reaction has also been applied to certain other morphine derivatives. Reduction of the didehydro-compounds with sodium borohydride in the presence of tritiated water gave the [15-3H]-derivatives.
