General description

This resin is ideal for the solid phase immobilization of carboxylic acids. Less cross-linking is observed than with Merrifield resin during the attachment of diacids [1]. Reaction with a suitable phosgene equivalent converts this resin to a support suitable for the immobilization of amines [2].

Release of carboxylic acids from this support is normally effected by treatment of the resin with HF or TFMSA, or by hydrogenolysis [3]. Alcohols can be liberated by reduction with DIBAL [4] or LiBH₄ [5]. Methyl esters can be produced by transesterification with MeONa [6] or Ti(OEt)₄/C₂H₅CO₂Me [7]. Carboxamides are also accessible via Lewis acid catalyzed aminolysis [8].

The product number for this product was previously 01-64-0110.
