Description

General description

DCC is the acronym for N,N′-dicyclohexylcarbodiimide. In peptide synthesis, it is utilized for the activation of carboxyl group. The structure of DCC has been analyzed based on IR and Raman spectral data. It mediates the esterification of poly(vinyl alcohol) with free levulinic acid to form poly(vinyl alcohol-co-vinyl levulinate).

Application

DCC has been used in the preparation of titanate nanotubes-phthalocyanine(TiONts-Pc) nanohybrids and 7-((tert-butyldimethylsilyl)oxy)hepta-2,4-diyn-1-yl propynoate.

DCC may be used to promote the esterification of
7-((tert-butyldimethylsilyl)oxy)hepta-2,4-diyn-1-ol with propiolic acid to form 7-((tert-butyldimethylsilyl)oxy)hepta-2,4-diyn-1-yl propynoate.
It can also used to synthesize:

• 1,3-Thiazetedine derivatives via [2+2] cycloaddition with 2-phenylethenyl- and 2-(4-nitrophenyl)ethenyl isothiocyanates.
• 1,3,5-Oxadiazine-4-thiones via [4+2] cycloaddition with benzoyl isothiocyanates.
• Sterically hindered 1,3,4-oxadiazole derivatives by reacting with (N-isocyanimino)triphenylphosphorane in the presence of aromatic (or heteroaromatic) carboxylic acids.

Carboxy group activating reagent for peptide synthesis.
