The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle.

The article 《Chiral Bidentate Boryl Ligand-Enabled Iridium-Catalyzed Enantioselective Dual C-H Borylation of Ferrocenes: Reaction Development and Mechanistic Insights》 in relation to this compound, is published in ACS Catalysis. Let’s take a look at the latest research on this compound (cas:60748-47-2).

Ferrocenes with planar chirality are an important class of privileged scaffolds for diverse chiral ligands and organocatalysts. The development of efficient catalytic asym. methods under mild reaction conditions is a long-sought goal in this field. Though many transition-metal-catalyzed asym. C-H activation methods were recorded during the last decade, most of them are related to C-C bond-forming reactions. Owing to the useful attribute of the C-B bond, the authors herein report an amide-directed Ir-catalyzed enantioselective dual C-H borylation of ferrocenes. The key to the success of this transformation relies on a chiral bidentate boryl ligand and a judicious choice of a directing group. The current reaction could tolerate a vast array of functionalities, affording a variety of chiral borylated ferrocenes with good to excellent enantioselectivities (35 examples, up to 98% enantiomeric excess). The authors also demonstrated the synthetic utility by preparative-scale reaction and transformations of a borylated product. Finally, from the observed exptl. data, the authors performed DFT calculations to understand its reaction pathway and chiral induction, which reveals that Me C(sp3)-H borylation is crucial to conferring high enantioselectivity through an amplified steric effect caused by an interacted B-O fragment in the transition state.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Tetrahedron called Synthesis and characterization of an isopropylBippyPhos precatalyst, Author is Coffey, Steven B.; Bernhardson, David J.; Wright, Stephen W., which mentions a compound: 60748-47-2, SMILESS is O=C(/C=C/C1=CC=CC=C1)/C=C/C2=CC=CC=C2.O=C(/C=C/C3=CC=CC=C3)/C=C/C4=CC=CC=C4.O=C(/C=C/C5=CC=CC=C5)/C=C/C6=CC=CC=C6.[Pd].[Pd], Molecular C51H42O3Pd2, Category: catalyst-palladium.

A review of our high throughput reaction screening data revealed that BippyPhos was frequently associated with successful outcomes in Buchwald-Hartwig amination reactions. A barrier to the wider use of this ligand, particularly among those performing smaller scale work, may be the lack of a readily available precatalyst. We describe the multi-gram synthesis and characterization of isopropylBippyPhos, and its conversion to isopropylBippyPhos Pd G2, a biaryl phosphine precatalyst. We demonstrate the competency of isopropylBippyPhos Pd G2 in palladium catalyzed Buchwald-Hartwig amination reactions and in Suzuki-Miyaura cross-coupling reactions.
