Palladium reagents for bioconjugation
… residues with bis-palladium organometallic reagents. These synthetic intermediates are prepared in a single step from commercially available aryl bis-halides. Two bioactive linear peptides with cysteine residues at i, i + 4 and i, i + 7 positions, respectively, were cyclised to introduce a …

SENSORS BASED ON IMMOBILIZED FLUOROGENIC REAGENTS
… on the fluorescence of immobilized fluorogenic reagents are prepared and their characteristics are defined. The fluorogenic reagent is chemically immobilized on a solid support and attached to the common end of a bifurcated fiber optic bundle. Fluorescence is excited through one arm of the fiber …

Silenes: Novel Reagents for Organic Synthesis
Whilst silenes have long been studied for their unique chemistry there has been little attempt to exploit this in other synthetic strategies. As part of a programme to explore this aspect the reactions of readily accessible silenes with alkenes and dienes were studied. Silenes, generated by the …

Hypervalent iodine reagents for protein functionalisation
… of methionine-selective protein labelling reagents with improved reactivity and versatility, while enhancing the stability of the resultant protein conjugates. We have developed a new class of iodonium reagents wherein the ester motif is replaced with a ketone group. Our synthetic strategy …

Bioorthogonal Reagents: Design, Synthesis, and Reactivity
… development of new bioorthogonal reactions and reagents. In part 1, 5-membered cyclic Diels–Alder dienes are studied. This study ranges from the development of 4H-pyrazoles as bioorthogonal reagents to an exploration of the physical organic chemistry of 5-membered cyclic dienes that accelerate …

Development of Methods for Boron Reagents
Boron reagents are known to be valuable in the field of organic chemistry due to their abilities to undergo a variety of transformations, resulting in useful pharmaceuticals and synthetic intermediates. It has also been shown that diboron reagents can act as reaction mediators due to the unique …

Polymer-supported reagents for disinfection of water
A macroporous poly(styrene-co-divinylbenzene) resin having redox N,N-dichlorosulfonamide group, was modified for use in small-scale chlorination of potable water. The resin was synthesized via sulfonyl chloride by modification of the strong acid cation exchange resin, Amberlyst-15. The products …

Organotellurium Reagents for Multiparametric Interrogation of Dynamic Biology
Population-averaged measurements (PAMs) of cells have advanced understanding of innumerable biochemical processes and continue to be routinely used in the laboratory. Despite this success, PAMs are limited in their ability to report on the precise state of important individual members of a …

Asymmetric reduction using enzymes and Chiral chemical reagents
… the assessment of the efficiency of the chiral reagents. Two types were investigated a) borate complexes of β-amino alcohols and b) triacycloxyborohydrides prepared from chiral amino acids. The fomer gave modest chiral induction (up to 18% isomeric excess) whilst the latter were inert. The …
