A number of organoselenium reagents are introduced as efficient initiators of ringclosures leading from unsaturated substrates to lactones, cyclicethers, cyclic thioethers, N-heterocycles and carbocycles. These cyclizations often proceed with high ring selectivity and stereoselectivity and are accompanied by the incorporation of the phenylseleno group (PhSe) into the final product. Methods are described
