Chain walking of allylrhodium species towards esters during rhodium-catalyzed nucleophilic allylations of imines (2015)
Journal Article

Allylrhodium species derived from ?-trifluoroboryl ?,?-unsaturated esters undergo chain walking towards the ester moiety.The resulting allylrhodium species react with imines to give products containing two new stereocenters and a Z-alkene. By using a... Read More about Chain walking of allylrhodium species towards esters during rhodium-catalyzed nucleophilic allylations of imines.

Enantioselective Synthesis of Spiroindenes by Enol-Directed Rhodium(III)-Catalyzed C—H Functionalization and Spiroannulation (2015)
Journal Article

Chiral cyclopentadienyl rhodium complexes promote highly enantioselective enol?directed C(sp2)?H functionalization and oxidative annulation with alkynes to give spiroindenes containing all?carbon quaternary stereocenters. High selectivity between two... Read More about Enantioselective Synthesis of Spiroindenes by Enol-Directed Rhodium(III)-Catalyzed C—H Functionalization and Spiroannulation.

Direct Synthesis of 5-Aryl Barbituric Acids by Rhodium(II)-Catalyzed Reactions of Arenes with Diazo Compounds (2015)
Journal Article

A commercially available rhodium(II) complex catalyzes the direct arylation of 5?diazobarbituric acids with arenes, allowing straightforward access to 5?aryl barbituric acids. Free N--H groups are tolerated on the barbituric acid, with no complicatio...

Enantioselective copper-catalyzed reductive coupling of vinylazaarenes with N-Boc aldimines (2015)
Journal Article

The diastereo- and enantioselective reductive coupling of vinylazaarenes with N-Boc aldimines is described. The reactions proceed using chiral copper–bisphosphine complexes in the presence of TMDS as a hydride source to give reductive coupling produc...

Synthesis of spiroindanes by palladium-catalyzed oxidative annulations of non- or weakly activated 1,3-dienes involving C–H functionalization (2015)
Journal Article

The synthesis of spiroindanes by the palladium-catalyzed oxidative annulation of non- or weakly activated 1,3-dienes with 2-aryl cyclic 1,3-dicarbonyl compounds is described. Examples of the dearomatizing oxidative annulation of 1,3-dienes with 1-ary...
