2-Chlorotrityl chloride Chemical Properties,Usage,Production

Chemical Properties

off-white to yellow or brown beads

Uses

2-Chlorotrityl chloride is used as an intermediate of clotrimazole. It is also used in the preparation of modified trityl nucleosides as inhibitors of P. falciparum dUTPase. In addition, it serves as a protecting group reagent for carboxylic acids forming esters.

Application

2-Chlorotrityl Chloride is used in convergent peptide synthesis. Extremely acid labile resin for preparing peptide acids and partially protected peptide fragments by the Fmoc strategy. Cleavage can be effected by using AcOH/TFE/DCM or 0.5% TFA.

Preparation

2-Chlorotrityl chloride synthesis: It is esterified with 2-Chlorobenzoic acid and ethanol in the presence of sulfuric acid or p-toluenesulfonic acid to generate Ethyl 2-Chlorobenzoate, which is then condensed with phenylmagnesium bromide (Grignard reaction) to obtain (2-Chlorophenyl)diphenylmethanol magnesium salt is hydrolyzed with sulfuric acid to obtain (2-Chlorophenyl)diphenylmethanol, which is then chlorinated with thionyl chloride to obtain the product.

reaction suitability

reaction type: Fmoc solid-phase peptide synthesis

Biotechnological Applications

The 2-chlorotrityl chloride (2-CTC) resin is one of the most frequently used and most versatile resins for the large-scale manufacture of peptides. It is slightly less acid-labile than Trityl Resin and thus more widely used in solid phase peptide synthesis. Peptides UBI-8 and UBI-9 were synthesized by Fmoc-solid phase chemistry using a 2-chlorotrityl chloride linker-resin. Trityl linkers have certain advantages in comparison to the alkoxybenzyl alcohol (eg. Wang resin), especially in the area of peptide chemistry. First, the problem of racemization during the loading of the first amino acid (using DIPEA) is avoided with trityl linkers. Second, due to steric factors, no diketopiperazine formation is observed.
