Easily accessible dihydropyrans 9, 10, 12 and 19 are precursors for the synthesis of 6-substituted 5,6-dihydro-2 (2H)-pyranones and 6-substituted tetrahydro-2-pyranones. Syntheses of massoia lactone (3), argentilactone (5), tuberolactone (4) and jasmine lactone (2) from acrolein (6), acrolein dimer (7) or glutaraldehyde (16) are described.
容易接近二氢吡喃9,10,12和19是用于6-取代5,6-二氢-2-(2合成前体ħ)-pyranones和6-取代的四氢-2-吡喃酮。描述了由丙烯醛(6),丙烯醛二聚体(7)或戊二醛(16)合成马萨诸塞内酯(3),精氨酸内酯(5),结核内酯(4)和茉莉内酯(2)。
