Synthesis of Furanoid Terpenes via an Efficient Palladium-Catalyzed Cyclization of 4,6-Dienols

The total syntheses of marmelo oxides A and B and a terpene alcohol found in peppermint oil are described.The key steps in these syntheses are the regioselective palladium-catalyzed allylic substitution of 4 and 11 to 6a and 12, respectively, and the regioselective palladium-catalyzed cyclization of 8 and 14 to 9a, 9b, and 15, respectively.The relative stereochemistry of marmelo oxides A and B was established by NOE measurements.

The Enantioselective Synthesis of Marmelo Oxides A and B and the Assignment of the Absolute Configurations of Marmelo Oxides

(+)-Marmelo oxide A and (-)-marmelo oxide B were stereoselectively synthesized form D-glutamic acid via (-)-marmelo lactones A and B.The absolute configurations of marmelo oxides were thus determined to be the (+)-oxide A having the (2R,4R) and (+)-oxide B having (2S,4R) configuration.

Volatile Components of Quince Fruit (Cydonia oblonga Mill.)

Steam distilled oil of quince fruit (Cydonia oblonga Mill.= C. vulgaris Pers., marmelo in Japanese) was analyzed by gas chromatography and gas chromatography-mass spectrometry.Sixty-two compounds, 2 hydrocarbons, 13 esters, 11 alcohols, 11 aldehydes, 11 ketones, 5 lactones and 9 miscellaneous compounds, were indentified.Of them, the chemical structures of two new oxide compounds, trans- and cis-3-methyl-5-tetrahydrofuran, were elucidated by instrumental analyses.
