Asymmetric Allylation of Furfural Derivatives: Synergistic Effect of Chiral Ligand and Organocatalyst on Stereochemical Control

An asymmetric allylation reaction at the benzylic position of furfurals that are easily accessed from 5-HMF, which is a biomass derivative, has been established by palladium and amine cooperative catalysis. The high levels of enantioselectivity of up to 97% enantiometric excess (ee) were enabled by the synergistic stereochemical control of a chiral TADDOL-based phosphoramidite ligand and a chiral diphenylprolinol silyl ether. The product could be feasibly transformed to chiral aryl-substituted spiroacetal via a four-step reaction sequence.

Palladium-catalyzed dearomative trimethylenemethane cycloaddition reactions

A general protocol for the palladium-catalyzed dearomative trimethylenemethane [3+2] cycloaddition reaction with simple nitroarene substrates is described. This methodology leads to the exclusive formation of the dearomatized alicyclic products without subsequent rearomatization. The reaction is tolerant toward a broad range of heterocyclic and benzenoid substrates. The use of chiral bisdiamidophosphite ligands enabled the development of an enantioselective variant of this transformation, representing one of the rare examples of an asymmetric catalytic dearomatization process.

(E)- and (Z)-beta-borylallylsilanes by alkyne silaboration followed by regio- and stereoselective double-bond migration

Double take: beta-Borylallylsilanes have been synthesized by the regioselective silaboration of terminal alkynes followed by palladium-catalyzed double-bond migration of the resulting beta-borylalkenylsilanes (see scheme). The stereoselectivity of the double-bond migration can be controlled by additives, thus leading to the stereocomplementary synthesis of (E)- and (Z)-beta-borylallylsilanes. Copyright

Pd-catalyzed dearomative arylborylation of indoles

A palladium-catalyzed dearomative arylborylation of indoles is reported, which provides straightforward access to structurally diverse indolines bearing vicinal tetrasubstituted and borylated trisubstituted stereocenters in moderate to good yields with excellent diastereoselectivities. By using a BINOL-based chiral phosphoramidite ligand and an sp2-sp3 mixed-boron reagent, an enantioselective dearomative arylborylation was achieved and chiral boron-containing products were accessed in up to 94% ee. Synthetic tranformations of the resulting organoborons were conducted to afford a number of unique indoline derivatives.

Supramolecular Structure-Dependent Thermally-Activated Delayed Fluorescence (TADF) Properties of Organic Polymorphs

The increasing demand for high-performance organic light-emitting devices (OLEDs) based on thermally-activated delayed fluorescence (TADF) principle urgently requires to establish an efficient preparation strategy of high-performance TADF materials. Although considerable progress has been made in molecular design approaches for TADF materials, it still remains an unaddressed issue how molecular aggregated states or supramolecular structures determine the TADF property of organic solids. Herein, we present an organic molecule 3-(10H-phenoxazin-10-yl)-9H-xanthen-9-one (3-PXZ-XO) with TADF and polymorph characteristics. Three kinds of 3-PXZ-XO based crystals A, B, and C with different TADF properties were obtained. The three crystals display obviously different emission maxima (lambdaem,max: 535 nm for A, 555 nm for B, and 576 nm for C), photoluminescence (PL) quantum yields (phi: 51% for A, 28% for B, and 39% for C), and delayed lifetimes of excited states (tauTADF: 914 ns for A, 774 ns for B, and 994 ns for C). Single-crystal X-ray diffraction analyses revealed that in A, B, and C there are different intermolecular pi···pi stacking interaction modes between the adjacent donor planes or acceptor planes. The different TADF properties of the three polymorphs are mainly attributed to their different supramolecular structures. Appropriate donor···donor and acceptor···acceptor stacking interactions inducing aggregation structures can strongly enhance TADF property of organic solids.

Intramolecularly stabilised group 10 metal stannyl and stannylene complexes: Multi-pathway synthesis and observation of platinum-to-tin alkyl transfer

Reaction of [PdClMe(P?N)2] with SnCl2 followed by Cl-abstraction leads to apparent Pd-C bond activation, resulting in methylstannylene species trans-[PdCl{(P?N)2SnClMe}][BF4] (P?N = diaryl phosphino-N-heterocycle). In contrast, reaction of Pt analogues with SnCl2 leads to Pt-Cl bond activation, resulting in methylplatinum species trans-[PtMe{(P?N)2SnCl2}][BF4]. Over time, they isomerise to methylstannylene species, indicating that both kinetic and thermodynamic products can be isolated for Pt, whereas for Pd only methylstannylene complexes are isolated. Oxidative addition of RSnCl3 (R = Me, Bu, Ph) to M0 precursors (M = Pd or Pt) in the presence of P?N ligands results in diphosphinostannylene pincer complexes trans-[MCl{(P?N)2SnCl(R)}][SnCl4R], which are structurally similar to the products from SnCl2 insertion. This showed that addition of RSnCl3 to M0 results in formal Sn-Cl bond oxidative addition. A probable pathway of activation of the tin reagents and formation of different products is proposed and the relevancy of the findings for Pd and Pt catalysed processes that use SnCl2 as a co-catalyst is discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Bis(dibenzylideneacetone)palladium, you can also check out more blogs about32005-36-0

Palladium-catalyzed asymmetric allylic alkylation of acyclic ketones for synthesis of 2,2-disubsituted pyrrolidine derivatives

Palladium-catalyzed asymmetric allylic alkylation of acyclic ketones represents a significant challenge in organic synthesis. We report herein that the synthesis of chiral 2,2-disubsituted pyrrolidines from acyclic ketones has been accomplished by using catalytic asymmetric method in the presence of Pd(dba)2 and (R)-binap ligand. Theses reactions occur between allyl methyl carbonate and unstabilized acyclic lithium enolates to provide the products in moderate to good enantioselectivity (up to 81% ee).
