Polybrene® Technical Bulletin
Polybrene® is a well-known anti-heparin agent. Also known as 1,5-dimethyl-1,5-diazaundecamethylene polymethobromide and hexadimethrine bromide, this positively charged polymer produces non-specific red blood cell agglutination by neutralizing the red blood cell net negative charge.
Triazolylphenylglyoxal Reagents: Arginine-Directed Bioconjugation
Chemical ligation strategies are widely utilized for the modification of biological macromolecules in biotechnology and medicine, and in for the development of functional materials. In particular, reagents that can modify the surface of proteins, typically through reactive side chains, have
Inverse Electron Demand Diels–Alder Reactions of 1,2,4,5-Tetrazines and 1,2,3-Triazines
The inverse electron demand Diels-Alder reactions of electron-deficient heterocycles are significant cycloaddition reactions for the total synthesis of natural products containing highly substituted and functionalized heteroaromatic ring systems.
Fries Rearrangement
The Fries rearrangement reaction is an organic name reaction which involves the conversion of phenolic esters into hydroxyaryl ketones on heating in the presence of a catalyst. Suitable catalysts for this reaction are Brønsted or Lewis acids such as HF
Jørgensen’s Organocatalysts
Professor Karl Anker Jørgensen and his group have developed ethers which serve as excellent chiral organocatalysts in the direct asymmetric α-functionalization of aldehydes.
Knoevenagel Condensation Reaction
Knoevenagel Condensation is an organic reaction named after Emil Knoevenagel. It is a classic C-C bond formation reaction and a modification of the Aldol Condensation.
C–H Amination
The Du Bois group at Stanford University has made substantial progress within the field of Rh-catalyzed C–H amination via oxidative cyclization of carbamate, sulfamate, sulfamide, urea, and guanidine substrates to give 1,2- and 1,3-heteroatom motifs masked in the form of
