Photochemical Allylation of Aldehydes or Alkanes with Vinyl Cyclopropanes

ChemistryEurope, EarlyView.
An acylation or alkylation of vinyl cyclopropanes, employing tetra‐n‐butylammonium decatungstate as the photocatalyst, leading allyl ketones or alkenes is presented. A diverse range of substrates were compatible with this protocol, while flow conditions were also developed and mechanistic studies were also performed.

The Conformational Electrostatic Potential as Predictor for the Influence of Fluorination on Alcohol Hydrogen Bonding: Identification of a CF2H‐Mediated Cooperative Effect

ChemistryEurope, EarlyView.
With a little help… OH•••F intramolecular hydrogen bonding (HB) strongly reduces alcohol HB acidity, resulting in underestimation of predicted HB acidity based on the molecular Kenny electrostatic potential. In contrast, CF2H–OH intramolecular interaction causes a positive cooperative effect leading to HB acidity enhancement, as revealed by ...

Pivotal Synthesis of Tetrasubstituted Epoxides from Ketones and α‐Halo B/Si Ylides with Understanding of the Activation Modes

ChemistryEurope, EarlyView.
The preparation of diastereoselective 1,1,2,2‐tetrasubstituted borosilylepoxides is described, involving the epoxidation of ketones with α‐monohalo borylsilylmethane reagents. The nature of the ambiphilic reagent suppressed the Boron‐Wittig olefination.

Gold(I)‐Catalyzed Domino Cyclization for the Construction of Trispirocyclic Cyclohexanes

ChemistryEurope, EarlyView.
We describe herein a series of intricate trispirocyclic architectures that have been synthesized from readily available substrates through an operationally simple one‐pot transformation under mild conditions. An unprecedented gold(I)‐catalyzed domino cyclization involving 2‐ethynylbenzyl alcohol derivatives and heterocyclic α,β‐unsaturated imines ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...
