Reactions between lithiated 1,3-dithiane oxides and trialkylboranes

Autor: Basil A. Saleh, Gamal A. El-Hiti, Keith Smith, Mark Christopher Elliott

Publikováno v: Journal of Sulfur Chemistry. 42:591-603

Various 2-substituted-1,3-dithiane oxides (1-oxide and 1,3-dioxide) have been metalated and reacted for the first time with a trialkylborane (trioctylborane). The 2-chloro-1,3-dioxide results in migration of an octyl group from boron to carbon with t

Studies on a catalytic version of the Matteson asymmetric homologation reaction

Autor: Mohammed B. Alshammari, Mark Christopher Elliott, Gamal A. El-Hiti, Basil A. Saleh, Keith Smith

Publikováno v: Organic & Biomolecular Chemistry. 19:4279-4284

Studies of a catalytic asymmetric version of the Matteson reaction between dichloromethylboronates and organolithium reagents have been undertaken. From several different chiral catalytic systems studied, only one based on a mannitol derivative has g

Botulinum neurotoxins (BoNTs) are notorious toxins and powerful agents and can be lethal, causing botulism, but they are also widely used as therapeutics, particularly to treat neuromuscular disorders. As of today, the commercial BoNT treatments avai

BACKGROUND Numerous translocations of Eurasian beavers have occurred with little implementation of standardised health screening. Pre-release health screening enables the selection of individuals with the best survival prospects and reduces potential

Regioselective synthesis of important chlorophenols in the presence of methylthioalkanes with remote SMe, OMe or OH substituents

Autor: Keith Smith, Ali Jassim Al-Zuhairi, Mark Christopher Elliott, Gamal A. El-Hiti

Publikováno v: Journal of Sulfur Chemistry. 39:607-621

Various methylthio alcohols, methoxy(methylthio)alkanes and bis(methylthio)alkanes have been used as regioselectivity modifiers in the chlorination reactions of various phenols at room temperature. The process involves the use of a slight excess of s

Reactions of organoboranes with carbanions bearing three potential leaving groups: unusual processes, products and mechanisms

Autor: Dyfyr Heulyn Jones, Basil A. Saleh, Gamal A. El Hiti, Keith Smith, Mark Christopher Elliott, Benson M. Kariuki

Publikováno v: Tetrahedron. 72:6914-6928

Known reagents that transfer three alkyl groups of a trialkylborane intramolecularly to a single carbon atom lack features to influence stereochemistry. We have investigated four reagents of type LiCCl2X, where X might be amenable to variation. All b

Factors affecting reactions of trialkylcyanoborates with imidoyl chlorides/trifluoroacetic anhydride

Autor: Dyfyr Heulen Jones, Keith Smith, Gamal A. El-Hiti, Mark Christopher Elliott

Publikováno v: Tetrahedron. 71:6285-6289

Methods for generating tert-alkyl organoboron species are in high demand as they are invaluable intermediates for the synthesis of quaternary carbon centres. Herein we report investigations into generation of tert-alkyl organoboron species using imid
