Abstract
Ruthenium catalyzed ring opening cross-metathesis of resin-bound bicyclic alkenes with terminal aryl olefins was utilized for the construction of a combinatorial library containing highly functionalized cyclopentane derivatives. The technology described herein represents a convergent method for the diastereospecific synthesis of unique cyclopentane molecular scaffolds useful for exploratory medicinal chemistry.
