Abstract
A new sulfonyl radical-triggered 6-endo-trig cyclization of unactivated
1,5-enynes under catalytic oxidation conditions for flexible synthesis
of unprecedented unsymmetrical diaryl sulfones was established. This
transformation could also proceed smoothly using
2-arylalkynyl-1,1’-biphenyls, delivering new sulfonylated phenanthrenes.
The synthetic utility of these transformations results in subsequent C-S
and C-C bond-forming reactions to effectively build up functional
sulfones with potential significance.
