Abstract

Abstract: Single-crystal X-ray analysis of four alkenes that undergo stereoselective radical addition reactions are reported. The facial selectivity of radical additions to these alkenes is understood based upon their solid-state conformations. Alkenes which have a conformation placing a group at a position in space sterically protecting one of the faces from addition undergo radical addition with diastereofacial selectivity. The structures of the alkenes are ...
