Abstract

Easily accessible dihydropyrans 9, 10, 12 and 19 are precursors for the synthesis of 6‐substituted 5,6‐dihydro‐2 (2__H__)‐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.
