AI Article Synopsis

  • A new bifunctional ligand with chiral NHC and prolinol groups is developed for use in catalysis.
  • The ligand facilitates asymmetric allylic alkylation reactions with a Cu/Zn bimetallic complex, producing various γ-vinyl ketones selectively.
  • Computational calculations indicate that the interactions between the ligand and substrates enhance the reaction’s selectivity and efficiency.

Article Abstract

A new bifunctional ligand bearing chiral N-heterocyclic carbene (NHC) and prolinol moieties is presented. Utilizing the designed ligand, an in situ formed Cu/Zn hetero-bimetallic complex unlocks the asymmetric allylic alkylation reactions of allyl phosphates with zinc keto-homoenolates, leading to the formation of various γ-vinyl ketones with good regio- and enantio-selectivity. DF sT calculation supports that the chelation of allyl phosphates with catalyst promotes the S 2' addition and the ligand-substrate steric interactions account for the stereoselective outcome.

The catalytic performance of phosphate-stabilized WO-ZrO compositions in gas-phase glycerol dehydration has been investigated. Results show that varying WO concentrations direct the process towards either acrolein or allyl alcohol formation. Catalysts with low WO content exhibit strong Lewis acid sites (Zr and W), where these metal ions likely function as redox sites, facilitating glycerol hydrogenolysis to produce allyl alcohol.

Transition metal-catalyzed cross-couplings have great potential to furnish complex ethers; however, challenges in the C(sp)-O functionalization step have precluded general methods. Here, we describe computationally guided transition metal-ligand design that positions a hydrogen-bond acceptor anion at the reactive site to promote functionalization. A general cross-coupling of primary, secondary, and tertiary aliphatic alcohols with terminal olefins to furnish >130 ethers is achieved.

Prenylated-FMN (prFMN) is the cofactor used by the UbiD-like family of decarboxylases that catalyzes the decarboxylation of various aromatic and unsaturated carboxylic acids. prFMN is synthesized from reduced FMN and dimethylallyl phosphate (DMAP) by a specialized prenyl transferase, UbiX. UbiX catalyzes the sequential formation of two bonds, the first between N5 of the flavin and C1 of DMAP, and the second between C6 of the flavin and C3 of DMAP.

This study elucidates the pivotal role of terminal structures in -1,4-polyisoprene (PI) chains, contributing to the exceptional mechanical properties of Hevea natural rubber (NR). NR's unique networking structure, crucial for crack resistance, elasticity, and strain-induced crystallization, involves two terminal groups, ω and α. The proposed ω terminal structure is dimethyl allyl-(-1,4-isoprene), and α terminals exist in various forms, including hydroxy, ester, and phosphate groups.
