- Rhodium(III)-catalyzed cross-coupling of alkenylboronic acids and N -pivaloyloxylamides
-
Rh(III)-catalyzed umpolung amidation of alkenylboronic acids for the synthesis of enamides is reported. This reaction proceeds readily at room temperature and displays an extremely wide spectrum of functional group tolerance. With cooperation of hydrobora

- Ruthenium-catalyzed addition of primary amides to alkynes: A stereoselective synthesis of secondary enamides
-
The anti-Markovnikov addition of primary amides to terminal alkynes under the formation of Z-configured secondary enamides is efficiently promoted by a catalyst system generated in situ from bis(2-methallyl)(cycloocta-1,5-diene) ruthenium(II), 1,4-bis(dic

- Synthesis of secondary enamides by ruthenium-catalyzed selective addition of amides to terminal alkynes
-
(Chemical Equation Presented) Enamides made easy: A catalyst system generated in situ using bis(2-methallyl)-(cycloocta-1,5-diene)ruthenium(II), 1,4-bis(dicyclohexylphosphino)butane, and ytterbium triflate efficiently catalyzes the addition of primary amides to terminal alkynes, selectively forming the Z-anti-Markovnikov enamides. The E isomers are also accessible by combining the hydroamidation with an in situ double-bond isomerization reaction.
