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

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
Kujawa, S., Best, D., Burns, D. J., & Lam, H. W. (2014). Synthesis of spirocyclic enones by rhodium-catalyzed dearomatizing oxidative annulation of 2-alkenylphenols with alkynes and enynes. Chemistry - A European Journal, 20(28), https://doi.org/10.1002/chem.201403454

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...

Enantioselective synthesis of allylboronates and allylic alcohols by copper-catalyzed 1,6-boration (2014)
Journal Article
Luo, Y., Roy, I. D., Madec, A. G., & Lam, H. W. (2014). Enantioselective synthesis of allylboronates and allylic alcohols by copper-catalyzed 1,6-boration. Angewandte Chemie International Edition, 53(16), https://doi.org/10.1002/anie.201310380

Chiral secondary allylboronates are obtained in high enantioselectivities by the copper-catalyzed 1,6-boration of electron-deficient dienes with B2(pin)2. The reactions proceed efficiently using catalyst loadings as low as 0.0049 mol%. The allylboron...

A second-generation ligand for the enantioselective rhodium-catalyzed addition of arylboronic acids to alkenylazaarenes (2014)
Journal Article
Roy, I. D., Burns, A. R., Pattison, G., Michel, B., Parker, A. J., & Lam, H. W. (2014). A second-generation ligand for the enantioselective rhodium-catalyzed addition of arylboronic acids to alkenylazaarenes. Chemical Communications, 50(22), https://doi.org/10.1039/C4CC00340C

A 2,4,6-trialkylanilide-containing chiral diene has been identified as a superior ligand for the enantioselective rhodiumcatalyzed arylation of alkenylazaarenes with arylboronic acids.
