Villeneuve, Karine; Tam, William published the article 《Asymmetric induction in ruthenium-catalyzed [2 + 2]-cycloadditions between bicyclic alkenes and a chiral acetylenic acyl sultam》. Keywords: alkyne bicyclic alkene cycloaddition; fused cyclobutene asym preparation; ruthenium cycloaddition catalyst.They researched the compound: Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium( cas:92390-26-6 ).Formula: C18H28ClRu. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:92390-26-6) here.
Tricyclic cyclobutenes, e.g., I were isolated from the ruthenium-catalyzed [2 + 2]-cycloaddition of bicyclic alkenes with a chiral acetylenic acyl sultam. The cycloaddition occurred with high stereoselectivity and high levels of asym. induction after removal of the chiral auxiliary.
This literature about this compound(92390-26-6)Formula: C18H28ClRuhas given us a lot of inspiration, and I hope that the research on this compound(Chloro(1,5-cyclooctadiene)(pentamethylcyclopentadienyl)ruthenium) can be further advanced. Maybe we can get more compounds in a similar way.
