Cross Metathesis Route in Sphingomyelin Synthesis
Chemistry Letters, 2004Abstract 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.

Metathesis and cross-metathesis of 5-acetoxy- or 5-cyanonorbornene
Journal of Molecular Catalysis, 1992Abstract Ring-opening metathesis polymerization (ROMP) of 5-cyanonorbornene (CNB) with the catalyst system tungsten hexachloride/diethylaluminium ethoxide proceeds with high selectivity and activity (CNB:W = 10200:1). The three-component catalyst system tungsten oxytetrachloride/methylaluminoxane/tetraisobutyldialuminoxane is suitable for ...

Ring closing metathesis and cross metathesis of carbohydrate derivatives
Tetrahedron Letters, 1998Abstract 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.

Cross-metathesis and ring-closing metathesis of olefinic monosaccharides
Tetrahedron Letters, 2002Cross-metathesis (CM) of a variety of carbohydrate-based C-6 and olefins with related C-1 and C-6 carbohydrate-based olefins proved to be unselective. CM was selective when an unhindered straight chain olefin was coupled with a carbohydrate-based C-6 olefin.
