MURGANTIOL AS A STINK BUG SYNERGISTIC ATTRACTANT FOR USE OUTDOORS

Provided herein are uses of the Harlequin bug pheromone, murgantiol, alone or in a synergistic combination with at least one other stink bug attractant, such as methyl (2E,4E,6Z)-decatrienoate or methyl (2E,4Z)-decadienoate, or both, for attracting stink bugs such as the brown marmorated stink bug in outdoor settings. Stink bug traps comprising murgantiol, or synergistic compositions comprising murgantiol with at least one other stink bug attractant, and methods of using these compositions in traps outdoors are provided. Compositions comprising murgantiol are also described as synergistic combinations of murgantiol with at least one other stink bug attractant.

Efficient Syntheses of β-Sesquiphellandrene and Zingiberenol Employing a Tandem Arylation-Multistep Reduction-Hydrolysis Sequence

The title sesquiterpenes are synthesized in one step from the common intermediate 4-(6-methyl-5-hepten-2-yl)-2-cyclohexen-1-one, which is prepared using a one-pot tandem arylation-multistep reduction-hydrolysis sequence.

Regiocontrolled Synthesis of Mono-, Di, and Trisubstituted Cyclohexenones by Cycloaddition of Vinyl Sulfones to 1-Methoxy-3--1,3-butadienes. Conversion of Alkenes into Effective Dienophilic Reagents

Cycloaddition of phenyl vinyl sulfone to Danishefky's diene followed by direct ketalization provided 7, a synthon for the 4-(2-cyclohexenyl) anion.Thus, 7 readily undergoes regiospecific γ-alkylation.Ensuing reductive desulfonylation and hydrolysis provides 2-(and 3-)-cyclohexenones efficiently.Zingiberenol, a monocyclic sesquiterpene, was prepared by means of this methodology.Terminal alkenes and cyclic olefins enter into comparable regiocontrolled Diels-Alder addition if they are first subjected to selenosulfonation and oxidation to the vinyl sulfone.Removal of the phenylsulfonyl substituent after condensation provides the adducts which are formally derived from alkylation of the hypothetical C5 anion of 2-cyclohexenone.The scheme can be expanded to include γ-alkylation prior to desulfonylation.By this means, one is able to prepare 4,5-disubstituted 2-(and 3-)cyclohexenones where the nature of the pendant side chains can be widely varied.

A NEW SYNTHON FOR THE REGIOSPECIFIC γ-ALKYLATION OF 2-CYCLOHEXENONES. APPLICATION TO THE SYNTHESIS OF ZINGIBERENOL AND OXYGENATED BICYCLONONANES

The regiospecific γ-alkylation of γ-sulfonylcyclohexenone ketals is described and applied to various synthetic objectives.
