标题:Termite Trail Attractants: New Syntheses Of Racemic (E)-α-,(Z)-α-Andβ-Bisabolenes
摘要:Racemic (E)-Alpha-Bisabolene (E)(1) Was Synthetized Starting From 4-Methyl-3-Cyclohexenecarboxylic Acid (3) By A Reaction Sequence Involving The Pd(0)-Catalyzed Cross-Coupling Reaction Between The (E)-2-Methyl-1-Alkenyltrimethylstannane 8 And 3-Methyl-2-Buten-1-Yl Acetate (9). Three Different Procedures,In Which A Common Precursor Was Used As Key Intermediate,Were Tested For The Synthesis Of Racemic (Z)-Alpha-Bisabolene (Z)(1). The Best One,Which Involved The Reaction Between Bromide 18 And Lithium Dialkenylcuprate 19,Afforded A Mixture Of (Z)-And (E)-1 In A 93:7 Molar Ratio,Respectively. Finally,Racemic Beta-Bisabolene (2) Was Synthetized By A Simple Reaction Sequence Involving The Zr-Promoted Methylenation Of Ketone 22 Prepared From 3.
