Easily accessible dihydropyrans undergo oxidation with PDC/t-BuOOH to yield the corresponding 5,6-dihydro-2-(2H)-pyranones in good yield. The methodology is exemplified with the synthesis of α-pyrone, (±)-argentilactone and (±)-goniothalamin.
容易获得的二氢吡喃经PDC / t-BuOOH氧化,以高收率得到相应的5,6-二氢-2-(2H)-吡喃酮。该方法以α-吡喃酮,(±)-精氨酸内酯和(±)-角硫胺素的合成为例。
