《Intramolecular alkene-alkyne metathesis and 1,4-cis-hydrogenation as a stereocontrolled route to compounds with exocyclic double bonds》 was written by Vasil’ev, A. A.; Engman, L.; Serebryakov, E. P.. Category: chlorides-buliding-blocks And the article was included in Russian Chemical Bulletin in 2020. The article conveys some information:
A (propargyl)butenylmalonate I underwent chemoselective ring-closing enyne metathesis in the presence of the first-generation Grubbs metathesis catalyst followed by diastereoselective hydrogenation in the presence of (η6-naphthalene)Cr(CO)3 to yield the (E)-ethylidenecyclohexanedicarboxylate II. Sequential ring-closing enyne metathesis and stereoselective hydrogenation is thus validated in a model system for the diastereoselective preparation of cyclic compounds with exocyclic alkenes. The results came from multiple reactions, including the reaction of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Category: chlorides-buliding-blocks)
Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9) is a ruthenium-based olefin metathesis catalyst. It is useful for olefin cross metathesis (CM) and ring closing metathesis (RCM) of terminal olefins under a variety of reactions conditions, and so on.Category: chlorides-buliding-blocks
