Two methodologies, likely to enhance the diastereoselectivity of sultonyl radical mediated cyclization of dienes 8 and 11, were investigated. Quaternization provided the expected result whatever the nature of the radical acceptingdouble bond, so did complexation of 11 with BF 3 or AIMe 3. A more str
