6-Amyl-α-pyrone, also 6-pentyl-2-pyrone or 6PP, is an unsaturated lactone molecule. It contains two double bonds in the ring and a pentyl substituent at carbon adjacent to the ring oxygen. [1] It is a colorless liquid which possesses characteristic coconut aroma, produced biologically by Trichoderma species. [2] [3] It is found in animal foods, peach ( Prunus persica), and heated beef. [4]
Chemically, 6PP is converted into a linear ketone via ring opening and decarboxylation in presence of water, which subsequently undergoes solid base catalyzed aldol condensation reaction into C14/C15 hydrocarbon precursor. [5] Upon heating in presence of Pd/C catalyst with formic acid, the double bonds of the 6PP get reduced to yield the flavoring compound δ-decalactone. [6] In presence of strong reducing agent like lithium aluminium hydride, the double bonds of the ring get saturated and transformed into 1,5-decanediol via sequential hydrogenation steps. [7]
