Tandem cyclopropanation/ring closing metathesis, enyne metathesis: Developments and application towards natural product synthesis
Chapter one. Tandem cyclopropanation/ring-closing metathesis of dienynes . Certain dienynes give cyclorearrangement by tandem cyclopropanation/ring-closing alkene metathesis, triggered by either a ruthenium carbene or ...
The development of tandem reactions involving enyne metathesis to form substituted cyclic dienes
Enyne metathesis provides direct access to conjugated 1,3 dienes of varying substitution patterns under mild conditions. Our primary focus involves enyne metathesis catalyzed by the Grubbs-type carbene complexes. The ...
Ring synthesis by intermolecular methylene-free tandem enyne metathesis
Enyne metathesis provides an expedient atom-economical synthesis of 1,3-dienes. With the advent of functional group tolerant, highly active ruthenium-based catalyst systems, enyne metathesis has been applied to more and ...
