Electrophilic Fluorination of Stereodefined Polysubstituted Silyl Ketene Hemiaminals en route to Tertiary ?-Fluorinated Carbonyl Derivatives

Org. Biomol. Chem., 2018, Accepted ManuscriptDOI: 10.1039/C8OB00067K, CommunicationIlan Marek, Jian Qiang Huang, Zackaria NairoukhThe highly diastereoselective synthesis of tertiary ?-fluoro carbonyl compounds is reported in only two chemical steps from a simple alkyne through the reaction of stereodefined fully substituted silyl ketene hemiaminal...The content of this RSS Feed (c) The Royal Society of Chemistry

Computational evidence for a reaction pathway bifurcation in Sasaki-type (4+3)-cycloadditions.

Org. Biomol. Chem., 2018, Accepted ManuscriptDOI: 10.1039/C8OB00075A, PaperJed Marcus BurnsThe current report seeks to validate the existence of a post-transition state bifurcation in the Lewis acid-catalysed (4+3)-cycloaddition of butadiene and [small alpha]-methoxy acrolein. Cycloaddition transition state (TS) structures are shown...The content of this RSS Feed (c) The Royal Society of Chemistry

Franch Andersen, Irene Boos, Christine Kinnaert, Shahid Awan, Henriette Pedersen, Stjepan K Kracun, Gyrithe Lanz, Maja G Rydahl, Louise Kjaerulff, Maria Hakansson, Raymond Kimbung, Derek Logan, Charlotte Gotfredsen, William George Tycho Willats, Mads Hartvig Hartvig ClausenWe report the synthesis of linear and branched (1[rightward arrow]4)-D-galactans.

E-Z isomerization in Suzuki cross-couplings of haloenones: Ligand effects and evidence for a separate catalytic cycle.

Org. Biomol. Chem., 2018, Accepted ManuscriptDOI: 10.1039/C7OB02925J, PaperNavneet Chehal, Peter H M Budzelaar, Philip HultinSuzuki cross-coupling of haloalkenes is generally assumed to occur with retention of the alkene stereochemistry. While studying Suzuki cross-couplings on E-1,2-dichlorovinyl phenyl ketone, we were surprised to observe extensive isomerization....The content of this RSS Feed (c) The Royal Society of Chemistry

New mechanism for internal nucleophilic substitution reactions.

Org. Biomol. Chem., 2018, Accepted ManuscriptDOI: 10.1039/C7OB02994B, PaperRamon J. Zaragoza, Maria Jose Aurell, Miguel A Gonzalez-CardeneteA new mechanism of the classic internal nucleophilic substitution reactions SNi by means of computational studies in gas-phase, DCM and acetonitrile is reported. Despite the importance of the SNi mechanism,...The content of this RSS Feed (c) The Royal Society of Chemistry
