일반 설명

DCC is an organic compound widely used as a coupling reagent in peptide synthesis. It is also employed as an efficient dehydrating agent for the preparation of amides, esters, nitriles, and anhydrides. Alcohols can be converted into aldehydes and ketone by Moffatt oxidation reaction in the presence of DCC and dimethyl sulfoxide (DMSO).

애플리케이션

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 may be 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 the presence of aromatic (or heteroaromatic) carboxylic acids.

Coupling Reagents

In principle, the seemingly simple formation of a peptide bond can be accomplished using all the procedures available in organic chemistry for the synthesis of carboxylic acid amides. However, due to the presence of various functional groups in natural and unnatural amino acids and particularly the requirement for full retention of chiral integrity, the coupling of amino acids and peptides under mild conditions can be challenging. A plethora of coupling reagents has been developed superseding each other in efficiency and suitability for specific applications (e.g., solid-phase peptide synthesis or fragment condensation).
