A Tandem Cross-Metathesis/Semipinacol Rearrangement Reaction
, 2016 An efficient and (E)-selective synthesis of a 6-alkylidenebicyclo[3.2.1]octan-8-one has been developed. The key step is a tandem cross-metathesis/semipinacol rearrangement reaction, wherein the Hoveyda–Grubbs II catalyst, or more likely a derivative ...

Geminal Alkene–Alkyne Cross Metathesis Using a Relay Strategy
, 2016 A relay strategy was employed to achieve an intermolecular ene–yne metathesis between 1,1-disubstituted alkenes and alkynes. The relay serves to activate an unreactive alkene which will not participate in ene-yne metathesis.
