Diels–Alder Reaction
The Diels–Alder reaction is the reaction between a conjugated diene and an alkene (dienophile) to form unsaturated six-membered rings. It is also referred to as a cycloaddition.
Aldol Condensation Reaction
The aldol condensation reaction is an organic reaction introduced by Charles Wurtz, who first prepared the β-hydroxy aldehyde from acetaldehdye in 1872.
Friedel–Crafts Acylation
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.
Baeyer-Villiger Oxidation Reaction
The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
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.
1-hydrosilatrane
As a versatile hydride reagent, 1-hydrosilatrane can be used in reduction reactions to synthesize alcohols, amines, their chiral counterparts, and esters from aldehydes/ketones.
Unnatural Amino Acids for Peptide Synthesis
Unnatural amino acids, the non-proteinogenic amino acids that either occur naturally or are chemically synthesized, are becoming more and more important as tools for modern drug discovery research.
