Synthesis of (2R,4R)-Supellapyrone, the Sex Pheromone of the Brownbanded Cockroach,Supella longipalpa, and Its Three Stereoisomers
摘要:
Supellapyrone [(2R,4R)-5-(2,4-dimethyl)-3-methyl-2H-pyran-2-one (1)], the female sex pheromone of the brownbanded cockroach (Supella longipalpa), and its three stereoisomers were synthesized by employing Iipase-catalyzed desymmetrization or enantiomer separation of syn- or anti-2,4-dimethylpentane- 1,5-diol (9) as the key step.
Lipase-catalyzed acetylation of a twice-prochirally shaped tetraol, 1, gave a mixture of diastereomeric diacetates from which an optically pure derivative belonging to the C2-symmetry group could be isolated.

Serricornin [(4S,6S,7S)-7-hydroxy-4,6-dimethyl-3-nonanonel, the female sexpheromone of Lasioderma serricorne, was synthesized by starting from (2S,4S)-2,4-dimethyl-1,5-pentanediol that had been obtained by lipase-catalyzed enantiomer separation of its racemate.
