Abstract
Functionalized allylic olefins are condensed by metathesis using the catalyst 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene ruthenium benzylidene [Ru*]. 1
Claims30
A method for condensing a functionalized allylic olefin substrate by metathesis chemistry, the method comprising the steps of:
- (a) providing a functionalized allylic olefin substrate;
- (b) providing a ruthenium-based catalyst capable of catalyzing the metathesis condensation of the functionalized allylic olefin substrate;
- (c) contacting the functionalized allylic olefin substrate with the catalyst to form a reaction mixture;
- and
- (d) placing the reaction mixture under conditions that result in the formation of a functionalized olefin product via metathesis condensation, the functionalized olefin product having a different chemical structure than the functionalized allylic olefin substrate.
