Catalytic 1,4-rhodium(III) migration enables 1,3-enynes to function as one-carbon oxidative annulation partners in C-H functionalizations (2014)
Journal Article
Burns, D. J., & Lam, H. W. (2014). Catalytic 1,4-rhodium(III) migration enables 1,3-enynes to function as one-carbon oxidative annulation partners in C-H functionalizations. Angewandte Chemie International Edition, 53(37), https://doi.org/10.1002/anie.201406072

1,3?Enynes containing allylic hydrogens cis to the alkyne are shown to act as one?carbon partners, rather than two?carbon partners, in various rhodium?catalyzed oxidative annulations. The mechanism of these unexpected transformations is proposed to o...

Synthesis of spirocyclic enones by rhodium-catalyzed dearomatizing oxidative annulation of 2-alkenylphenols with alkynes and enynes (2014)
Journal Article

The dearomatizing oxidative annulation of 2-alkenylphenols with alkynes and enynes proceeds with high yields and regioselectivities under Rh(III) catalysis. These reactions are successful using Cu(OAc)2 or air as the stoichiometric oxidant, and provi...
