- Versatile enantioselective synthesis of four diastereomers of serricornin, a sex pheromone of the cigarette beetle, using the SAMP/RAMP-hydrazone method
-
Serricornin is a female-produced sex pheromone of the cigarette beetle (Lasioderma serricorne), which is a pest of dried foodstuffs and tobacco. We report a versatile and short synthesis of all possible 6,7-syn-isomers of serricornin, including the natura

-
The synthesis of (4R,6S,7R)-7-hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5-dimethyl-2-octanone is described as their acetates using a desymmetrization strategy as well as an Evans syn aldol strategy.

- AN EFFICIENT AND STEREOSELECTIVE TOTAL SYNTHESIS OF (+/-)-SERRICORNINE
-
An efficient and stereoselective total synthesis of (+/-)-serricornine (1) the sex pheromone produced by the female cigarette beetle Lasioderma serricorne F, is described. (3SR,5SR,6SR)-6-Ethyltetrahydro-3,5-dimethyl-2H-pyran-2-one (10) is prepared in 65percent yield through lactonization of a 1:1 mixture of C-2 epimrs of the corresponding esters.
