Cross-Metathesis Assisted by Microwave Irradiation

The Journal of Organic Chemistry, 2005
Microwave irradiation effectively accelerates cross-coupling metathesis reactions between deactivated olefins. Reactions have been carried out with the phosphine-free Hoveyda-Grubbs catalyst and the "second generation Grubbs' catalyst." While there have been reports that a "microwave effect" is observed in various transformations, the accelerations we ...

Cross Metathesis Route in Sphingomyelin Synthesis

Chemistry Letters, 2004
Abstract Cross metathesis reaction of short chain Boc sphingosine using Grubbs’ 2nd generation catalyst proceeded in stereoselective manner to afford Boc sphingosine in good yield. An efficient synthesis of sphingomyelin was achieved from the obtained Boc sphingosine using our own phosphorylation reagent.

Synthesis of Vinyl‐Functionalized Thiazoles by Cross‐Metathesis and Tandem Stille Coupling/Cross‐Metathesis

Advanced Synthesis & Catalysis, 2007
AbstractThe application of olefin cross‐metathesis to vinyl‐functionalized thiazoles and the tandem Stille coupling/cross‐metathesis of bis‐trifloylthiazoles are reported. These processes offer new opportunities for the synthesis of complex natural products.

Ring closing metathesis and cross metathesis of carbohydrate derivatives

Tetrahedron Letters, 1998
Abstract In connection with the synthesis of annonaceous acetogenins and analogs, RCM of unsaturated esters has been studied with the Grubbs benzylidene carbene catalyst to give 9 to 15 membered lactones in moderate to good yield. Cross metathesis between 2 carbohydrate derivatives and methyl undec-10-enoate is also reported.
