A novel synthesis of 2,3-disubstituted benzopyran-4-ones and application to the solid phase

The development of a novel synthesis of 2,3-disubstituted benzopyran-4- ones and application to the solid phase are reported. Following model studies using benzyl alcohol as a surrogate for polystyrene hydroxymethyl resin, we utilized our previously established traceless diisopropylsilyloxy tinker methodology to synthesize a small library of target benzopyranones in generally high yield and purity.
