  A new synthon for optically active diene hydroperoxides

  摘要：

  The olefination of an enzymatically derived gamma-peroxy-alpha,beta-unsaturated aldehyde (1) allows the synthesis of optically active diene hydroperoxides in high enantiomeric excess. The application of this method to the synthesis of 13(S)-hydroperoxy-9(Z),11(E)-octadecadienoic acid methyl ester is presented.

• A Chemoenzymic Approach to Hydroperoxyeicosatetraenoic Acids. Total Synthesis of 5(S)-HPETE

  A new synthetic approach to enantiomerically pure hydroperoxyeicosatetraenoic acids (HPETEs) is described in which the tetraene skeleton is assembled through chemoselective olefination of a protected hydroperoxy aldehyde. Soybean lipoxygenase-mediated dioxygenation of both natural and unnatural fats produces hydroperoxy dienes in high enantiomeric excess; the observed regioselectivity supports a revised hypothesis for substrate specificity. Protection of the diene hydroperoxides as peroxy ketals is followed by regioselective ozonolysis to afford enantiomerically pure 4-peroxy 2,3-enals which undergo olefination to produce peroxytetraenoates. Removal of the monoperoxy ketal and the methyl ester affords enantiomerically pure HPETEs. The generality of the strategy is illustrated with the first chemical synthesis of 5(S)-HPETE.
• An organometallic approach to peroxy ketals

  A new method for peroxyketal synthesis is presented based upon formation of carbon-carbon bonds in the presence of a protected hydroperoxide. The 2-methoxypropyl perketal of 4(S)-hydroperoxy-2(E)-nonenal (2) undergoes reaction with a variety of metal hydrides and organometallic reagents to produce 4-peroxy 2-enols in good to excellent yields via chemoselective addition to the carbonyl carbon. Oxidation of the allylic alcohol to the 4-peroxy 2-enone is followed by deprotection to furnish a single enantiomer of a 4-hydroxyperoxy 2(E)-enone. Photochemical isomerization by the method of Snider induces spontaneous cyclization to epimeric 3-hydroxy-1,2-dioxins (hydroxy endoperoxides). Acidic methanolysis furnishes readily separable diastereomeric perketals as single enantiomers.
