| Sulfonyl chloride resin is a widely used reagent and can be applied in organic synthesis. It can react with alcohols to generate polymer-supported tosylates, which can then be cleaved with nucleophiles to generate secondary and tertiary amine, thioethers and N-alkylimidazoles [1-3]. This approach has been employed to prepared oxazolidinones by a cyclative cleavage strategy involving intramolecular aminolysis of the polymer-bound tosylate [4]. It can also be used as an efficient solid-supported condensation reagent for the solution phase synthesis of esters [5] or a derivative azide transfer reagent to prepare α-diazo ketones [6]. Chiral amine can also be supported on this resin to reduce the aromatic ketone to secondary alcohols [7]. References [1] J. J. Reuter, et al., Tetrahedron Lett., 1998, 39, 975 [2] E. W.
