Regioselectivity of ring closure of 2-thia- and 2-sulfonyl-5-methyl-5-hexenyl radicals
Della, Ernest W.,Graney, Sean D.
, p. 4065 - 4067 (2002)
(matrix presented) Ring closure of the α-substituted radicals 4 (X = S, SO2) is observed to be irreversible and to lead to significant amounts of the product of 6-endo cyclization. Indeed, reduction of the sulfonyl-based radical 4 (X = SO2
