Enamide−Olefin Ring-Closing Metathesis

Organic Letters, 2001
[reaction: see text] The first examples of ring-closing metathesis reactions of olefin-containing enamides using ruthenium-based catalysts have been demonstrated. A preliminary investigation into the scope and limitations, leading to protected five- and six-membered cyclic enamides, will be presented.

Heptane-Soluble Ring-Closing Metathesis Catalysts

Organic Letters, 2007
Terminally vinyl-functionalized polyisobutylene (PIB) oligomers can be easily transformed into end-functionalized PIB-bound Ru metathesis catalysts. The nonpolar catalysts so prepared can be used as solutions in heptane and recycled by a gravity-based extraction after addition of a heptane-immiscible polar solvent.

Ring-Closing Metathesis in Carbohydrate Annulation

Angewandte Chemie International Edition, 1998
Even eight-membered rings (such as in 2) can be formed by ring-closing metathesis of glucose derivatives such as 1. Enantiomerically pure tricyclic spiro compounds can also be prepared.

Ring-Closing Metathesis Approach to Dictyostatin

Organic Letters, 2005
[reaction: see text] An esterification/ring-closing metathesis approach to dictyostatin and discodermolide is introduced. The approach provides for facile fragment coupling of two main segments of these natural products at the C10-C11 alkene with high to complete Z-selectivity.
