• A high-pressure cycloaddition reaction of 1-acetyl-7-bromocyclohepta[<I>b</I>]pyrrol-2(1<I>H</I>)-one and 2,3-bis(methoxycarbonyl)-7-oxanorbornadiene and a further thermolysis of [4+2] cycloadducts gave 2-acetyl-9-bromo-2-azatricyclo[6.2.2.0<SUP>1,5</SUP>]dodeca-4,6,9,11-tetraen-3-one, which was photorearranged to 9-methylenebarbaralane and 5-methylenetricyclo[4.3.0.0<SUP>2,9</SUP>]nonadiene derivatives. The product distribution of the photolysis was altered by a bromine atom.
