We developed a facile approach for the preparation of a rare 2H-furo[3,2-b]pyran-2-one system. The suggested method is based on a two-step process using unsubstituted allomaltol as a starting compound. The key stage of the considered route is a condensation of 2-(2-aryl-2-oxoethyl)-3-hydroxy-6-methyl-4H-pyran-4-ones with 1,1-carbonyldiimidazole. The advantages of the presented method are commercially available starting materials and convenient experimental procedures including simple isolation of the target compounds. The structure of one of the 2H-furo[3,2-b]pyran-2-ones was confirmed by x-ray diffraction
