Abstract
Disclosed are a carrier for use for separation purpose and a method for separation of a compound which enable a chemical reaction to be performed in a liquid phase, enable a compound of interest to be separated from the liquid phase after the completion of the reaction readily, enable the separated compound to be evaluated by structural analysis or the like while the compound being bound to the carrier, and enable the compound to be separated from the carrier readily. A carrier for separation which has a reaction site capable of reacting with other compound on a benzene ring, and a long-chain group having a specified carbon atom(s) at each of the ortho-position and the para-position of the reaction site through an oxygen atom.
Claims5
A method for synthesizing an oligopeptide comprising:
- a dissolution process for dissolving a carrier for separation in a soluble solvent to prepare a carrier solution;
- wherein the carrier for separation is a compound having the following chemical formula (1),
- wherein the reaction site A is an atomic group having hydroxyl group, thiol group, amino group or carboxyl group which binds to an amino acid;
- X, Y and Z are hydrogen;
- and
- R1 and R2 are groups, which may be identical or different, containing at least 1 of a hydrocarbon group having a carbon number in the range of 14 to 60 which may have a substituent, and an acyl group having a carbon number in the range of 14 to 60 which may have a substituent;
- a binding process for obtaining the carrier for separation bound with an oligopeptide by binding an amino acid to the reaction site A of the carrier for separation and sequentially binding other amino acids to the amino acid which has been bound to the carrier for separation;
- a crystallization process for crystallizing the carrier for separation while the oligopeptide is bound to the carrier, or a selection process for selectively extracting and/or selectively crystallizing the carrier for separation into a specific phase while the oligopeptide is bound to the carrier;
- and
- after the crystallization process or the selection process, an excision process for excising the oligopeptide from the carrier for separation to which the oligopeptide has been bound.
