Purpose
1. Phenolic reagents. Organic Synthesis.
2. Diphenylcarbamoyl chloride (DPC-Cl) is a commonly used acylating reagent that can be used for Friedel-Crafts acylation; it can acylate amines, amino acids, thiols, phenols, and carboxylic acids Salt, etc.; can be used as a protective group during oligonucleotide synthesis, and the protective group can be removed under the action of concentrated ammonia-methanol or NaOH-methyl(ethanol) alcohol.
Introduction of carboxyl group Under the catalysis of AlCl3, DPC-Cl can introduce a carboxyl group on the aromatic ring. Alkyl or alkoxy substituted aromatic rings are susceptible to reaction. The product diphenylamide is hydrolyzed with alkali and then acidified to obtain carboxylic acid (formula 1)[1].
Reaction with amino groups DPC-Cl easily reacts with primary (formula 2) [2], secondary fatty amine (formula 3) [3] etc. [ 4~7].
Reaction with sulfhydryl group Under alkaline conditions (such as NaHCO3), DPC-Cl can react with thiols in ethanol solution (Formula 4)[8].
Used as oligomeric Protective groups during nucleotide synthesisWhen synthesizing oligonucleotides, the bases of guanine nucleosides are prone to side reactions and need to be protected. DPC-Cl can protect the enol isoforms of guanine bases. The conformation is protected by acylation. This method plays an important role in the synthesis of nucleoside compounds with guanine bases and those similar to guanine bases [9~12] ( Formula 5).
With double bonds Reaction of alcohol compounds DPC-Cl can undergo esterification reaction with alcohol compounds containing double bonds (Formula 6)[13].
With azide Reaction of sodium DPC-Cl can react with sodium azide to generate the corresponding azide compound (Formula 7)[14].
