Abstract
Benzocycloheptenones photoisomerise to strained trans-benzocycloheptenones which undergo smooth [ 4+2 ] cycloaddition with a variety of dienea. The adducts with cyclopentadiene can be readily transformed to trans fused 5-7-6 ring systems while cycloaddition with isoprene and 2-trimethylsilyloxy-1,3-butadiene produces directly trans fused 6-7-6 ring systems.
