Abstract
Polystyrene-SH resin, prepared from Merrifield resin in two steps, was converted to polystyrene-SO2-CH2-NC in three steps. This resin functions as a solid-phase equivalent of p-tolylsulfonylmethyl isocyanide (TosMIC). Thus, reaction with aromatic aldehydes and tetrabutylammonium hydroxide as base yields 5-aryloxazoles.
