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.
Amide bonds are ubiquitous in both nature and industrial applications. They are vital to the structure and function of biological macromolecules and polymers. The importance of this functionality has resulted in numerous approaches to its formation, ranging from stoichiometric activation
The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. Since the reaction involves the formation of a cyclic product via a cyclic transition state, it is also referred to as
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
