Rhodium-catalyzed regio- and stereoselective codimerization of alkenes and electron-deficient internal alkynes leading to 1,3-dienes.

Org. Lett. 10(13) , 2829-31, (2008)

A cationic rhodium(I)/H(8)-BINAP complex catalyzes codimerization of alkenes bearing no alpha-hydrogen and electron-deficient internal alkynes, leading to 1,3-dienes in good yields with moderate to ex...

Phosphine-catalyzed annulation of thioamides and 2-alkynoates: a new synthesis of thiazolines.

J. Org. Chem. 67(13) , 4595-8, (2002)

The annulation of thioamides with 2-alkynoates and 2,3-dienoates under the catalysis of tri-n-butylphosphine was described. The annulation reaction provided a new entry to thiazolines, particularly th...

Increases in microbial nitrogen production and efficiency in vitro with three inhibitors of ruminal methanogenesis.

Can. J. Microbiol. 53(4) , 496-503, (2007)

It was hypothesized that the addition of crotonic acid or 3-butenoic acid would relieve constraints in digestibility observed when methane formation is inhibited by lumazine, propynoic acid, or ethyl ...
