Inhaltszusammenfassung
The investigated set of 6-exo-trig cyclizations occurs irreversibly and justifies the use of tetrahydropyran-derived transition structures for rationalizing 2,6-cis, 2,5-trans, and 2,4-cis stereoselectivity in ring-closure reactions of 1-, 2-, and 3-phenyl-6-methyl-5-hepten-1-oxyl radicals.
