Org. Chem., 54, 1826, 3140 (1989). Compare analogous reductive cyclizations using the tin hydride. Improved conditions have been developed for generation of the tributylstannyl radical by mild UV irradiation in the presence of a triplet sensitizer (e.g. 4'-Methoxyacetophenone, A11162), allowing selective C-C bond forming reactions to be performed under free-radical conditions: Synlett, 287 (1993).
