SYNTHESIS OF ALL FOUR POSSIBLE ENANTIOMERS OF SITOPHILATE AGGREGATION PHEROMONE OF THE GRANARY WEEVIL

An efficient synthesis of the 3-pentyl ester of 2S-methyl-3R-hydroxypentanoic acid (sitophilate) and its 2S,3S-, 2R,3R-, and 2R,3S-isomers has been carried out starting from the available 2R-methyl-3-butenyl acetate as sole monochiral precursor.

DIASTEREOSELECTION IN 1,3-O- TO -C-ALKYL MIGRATION REACTION OF 1-ALKENYL ALKYL ACETALS CATALYZED BY BORON TRIFLUORIDE ETHERATE

Remarkable diastereoselection, with (E)-alkenyl alkyl acetal giving selectively the erythro α-alkyl-β-alkoxyaldehyde, and (Z)-acetal leading preferentially to the threo isomer, is observed in the 1,3-O- to -C-alkyl migration reaction of 1-alkenyl alkyl ac
