Kaden, Felix; Metz, Peter published their research in Organic Letters in 2021. The article was titled 《Enantioselective Total Synthesis of the Guaianolide (-)-Dehydrocostus Lactone by Enediyne Metathesis》.HPLC of Formula: 172222-30-9 The article contains the following contents:
The hydroazulene core of the bioactive sesquiterpenoid (-)-dehydrocostus lactone was generated by domino enediyne metathesis. A triple hydroboration/oxidation of the resultant conjugated triene installed three out of four stereogenic centers of the target in a single step. The enantiopure acyclic metathesis substrate was readily available by an asym. anti aldol reaction. Masking of the γ-lactone as an acetal allowed for an efficient completion of the synthesis through late-stage double carbonyl olefination. In the experimental materials used by the author, we found Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9HPLC of Formula: 172222-30-9)
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.HPLC of Formula: 172222-30-9
