Article abstract of DOI:10.1016/S0040-4039(00)92643-1

This paper reports straightforward syntheses of 1-aryl-bicyclo-[n. 1.0]-alkanes, 1-aryl-bicyclo-[3.3.0]-alkanes and of 1-phenyl-1,4-dimethyl-cyclopentane from unsaturated benzylselenides which involve the organolithiums-mediated cyclisation of olefins and
