Gold(I)/Xiang-Phos-Catalyzed Asymmetric Intramolecular Cyclopropanation of Indenes and Trisubstituted Alkenes

The first intramolecular enantioselective cyclopropanation of indenes and trisubstituted alkenes was accomplished by using new chiral phosphine X5 derived gold(I) complexes. This reaction is a straightforward, efficient method for constructing [5-3-6] fused-ring compounds with two vicinal all-carbon quaternary stereogenic centers, a core structure shared by numerous pharmacological products, and bioactive compounds. The salient features of this transformation include high enantioselectivity (up to >98% ee), excellent yield (>97%), and nice functional group tolerance.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 6974-97-6, help many people in the next few years.SDS of cas: 6974-97-6

Process for preparing 2-aryl-substituted indenes

A process is disclosed for preparing 2-aryl-substituted indenes by reacting an indene with an arene compound substituted with an halogen atom, preferably a iodine atom, or with an organosulphonate group, said reaction being carried out in a basic medium in the presence of a palladium catalyst. The compounds obtainable by this process can be used to prepare metallocene compounds with transition metals such as titanium, zirconium or hafnium, which are useful as catalyst components in the polymerization of olefins.

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 6974-97-6 is helpful to your research. Application of 6974-97-6

A chiral cagelike copper(I) catalyst for the highly enantioselective synthesis of 1,1-cyclopropane diesters

Triangulation method: The catalytic enantioselective cyclopropanation of multisubstituted olefins with phenyliodonium ylide malonate has been achieved in the presence of a chiral bisoxazoline copper(I) complex (see scheme). A wide range of substrates undergo the reaction to provide optically active 1,1-cyclopropane diesters in high yield with up to >99 %-ee. A rationale for the enantioselective induction has been proposed. Copyright
