General description
NovaSynTG carboxy resin is a composite of low cross-linked polystyrene and 3000-4000 M.W. polyethylene glycol, in which the ends of the PEG chains have been functionalized with carboxyl groups. The 130 μm beads have a narrow size distribution, high diffusion rates and excellent swelling properties across a wide range of solvents from toluene to water [1-3], making them ideally suited to the synthesis of serial and parallel libraries by organic solid phase synthesis.
This support can be used to immobilize alcohols through formation of an ester with the resin-bound carboxy group. Cleavage can be effected either by saponification, hydrazinolysis or reduction with LiBH4 .
In studies on the synthesis of furans via intramolecular radical cyclization, NovaSynTG carboxy resin was found to give superior results to carboxy polystyrene [4]. This observation was attributed to the notion that, in the PEG-based support, the radical intermediates would be prevented, by virtue of being tethered to the ends of PEG chains, from approaching and thus being quenched by the benzylic protons of the polystyrene backbone.
The product number for this product was previously 01-64-0097.
