摘要
Stereoselective syntheses of chiral C17 to C21 6 Z,9 Z-cis-3,4-epoxydienes were developed. Field tests of the enantiomerically enriched epoxides as components of synthetic sex attractant lures were carried out, and those with C17 and C19 chain lengths, particularly, were attractive to male moths of several species. Moths were usually specifically attracted by one of a pair of enantiomers, and the opposite enantiomer could actually be a behavioral antagonist. Males belonging to nine species of Geometridae were captured. Probole amicaria (Herrich-Schäffer) males were taken in traps baited with the mixture (6 Z,9 Z,3 S,4 R)-epoxy-nonadecadiene (6 Z,9 Z,3 S,4 R-epoxy-19:H) + 3 Z,9 Z,6 R,7 S-epoxy-19:H + 3 Z,6 Z,9 Z-19:H(9:1:8). Other species responding to the C19 compounds included (attractant components follow in parentheses);Sicya macularia (Harris) (6 Z,9 Z,3 S,4 R-epoxy-19:H + 3 Z,6 Z,9 Z-19:H), Anavitrinella pampinaria (Guenée) (6 Z,9 Z-cis-3,4-epoxy-19:H + 3 Z,9 Z,6 S,7 R-epoxy-19:H), and Lycia ursaria (Walker) (6 Z,9 Z-3 S, 4 R-epoxy-19:H + 3 Z,6 Z,9 Z-19:H). Males of the following species were captured by C17 epoxides:Itame occiduaria (Packard) (6 Z,9 Z,3 R,4 S-epoxy-17:H + 3 Z,6 Z,9 Z-17:H), Itame brunneata (Thunberg) (6 Z,9 Z,3 S,4 R-epoxy-17:H), Epelis truncataria (Walker) (both enantiomers of 6 Z,9 Z-cis-3,4-epoxy-17:H), Semiothisa ulsterata (Pearsall) (3 Z,9 Z-6 S,7 R-epoxy-17:H), and S. signaria dispuncta (Walker) (3 Z,9 Z-cis-6,7-epoxy-17:H + 3 Z,6 Z,9 Z-17:H). The interactions among enantiomers and regioisomers are discussed as a mechanism by which cross attraction between sympatric species is limited. © 1990 Plenum Publishing Corporation.
