Rearrangements of 2,3-Diazabicyclooctane Derivatives

The ketones 4a-e have been synthesized and their reactions with methylmagnesium iodide were studied.A mechanism is given for the rearrangement of some magnesium alkoxides to 6,7-diazabicyclooctane derivatives. - Dehydration of the alcohols 12d, 14a; 17a,b,g, and h with trichlorophosphane oxide is accompanied by migration of the group antiperiplanar to the hydroxy function, and thus 6,7-diazabicyclooctane derivatives are formed. - Ketones 4a,c and e give on sensitized irradiation the tricyclooctane derivatives 40a,b and d, respectively, while direct irradiation leads to the bicycloheptane derivatives 42a,b and d, respectively.
