A New Rare Example of Cyclopropanation in Free-Radical Chemistry
摘要:
Cyclic homoallylic radicals add on diene moieties according to a 3-exo-trig mode cyclization. The thus-formed radical, existing in two canonical forms, provides bicyclo[3.1.0] and -[4.1.0] skeletons. The formation of the thermodynamically most stable double bond may account for the chemoselectivity of this [2 + 1] cycloaddition reaction.
