n-2-one (K), and (E)-3-isopropyl-6-methyl-hepta-4,6-dien-1-ol (L). Compounds A–K were synthesized from norsolanadione (2), and compound L from 2-isopropyl-5-oxo-hexanal (15). The relative configuration of the bicyclic internal acetals B, C, F, G and their δ-keto-epoxide precursors A and E is discussed. All these Burley tobacco flavour components belong to a growing family of metabolites structurally
