Descrizione

Descrizione generale

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 H For 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/CH3CO2Me ^[7]. Carboxamides are also accessible via Lewis acid catalyzed aminolysis ^[8].
