General Description
3-Isochromanone has been reported to be isolated from the fungusNigrosporasp. PSU-F12.[1]An improved Knoevenagel condensation of 3-isochromanone with aromatic aldehydes has been achieved by microwave irradiation on solid supports in the presence of various catalysts.[2]Synthesis of 3-isochromanone via Beayer-Villiger rearrangement has been reported.
