Novabiochem® product range has one of the largest collections of orthogonally and quasi-orthogonally protected tri-functional amino acids. These derivatives are useful tools for the synthesis of cyclic and branched peptides and peptides carrying side-chain modifications.
Pressure conversion table and chart. The pressure converter is ideal for converting atm to pa, bar to psi, kpa to atm, atm to torr and other common units. Quickly convert units of pressure in the lab, classroom or field.
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
The Friedel–Crafts acylation is the reaction of an arene with acyl chlorides or anhydrides using a strong Lewis acid catalyst. This reaction proceeds via electrophilic aromatic substitution to form monoacylated products.
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.
