Chlorotrityl chloride resin
WebMay 14, 1998 · The laboratory synthesis of 2-chlorotritylchloride polystyrene resin was described. Polystyrene was acylated with 2-chlorobenzoyl chloride, reacted with phenyl lithium and finally converted to trityl chloride in the presence of dimethyl sulfoxide and trimethylsilyl chloride. A process for the regeneration of the resin is described. WebJan 15, 2007 · 2-Chlorotritylchloride (2-CTC) resin was prepared efficiently from 1% DVB-crosslinked polystyrene resin and 1-chloro-2- (dichloro (phenyl)methyl)benzene, which was easily obtained from 2-chlorobenzophenone. This 2-CTC resin showed excellent properties as a support for solid-phase peptide synthesis.
