INSECT PHEROMONES AND THEIR ANALOGS. XIII. SYNTHESIS OF DODEC-8E-ENYL AND DODEC-8Z-ENYL ACETATES - COMPONENTS OF THE SEX PHEROMONES OF Grapholitha funebrana AND Grapholitha molesta

A new route is proposed for the synthesis of dodec-8E-enyl and dodec-8Z-enyl acetates which is based on the reaction of the Grignard reagent from the readily accessible 1-bromo-5-(1-ethoxyethoxy)pentane with 1-bromohept-3-yne - the bromide obtained from product of the β-hydroxyethylation of pent-1-yne with 2-chloroethylvinyl ether, hept-3-yn-1-ol, by a double decomposition reaction of its tosylate with lithium bromide.The key synthon - dodec-8-yn-1-ol - was converted with the aid of sodium in liquid ammonia into the stereochemical individual dodec-8E-enol, while its reduction with the aid of 9-borabicyclononane (BBN) gave the stereoisomeric alcohol exclusively with the Z configuration, as followed from the results of capillary GLC and the IR spectra of the corresponding acetates.The PMR spectra of the compounds synthesized are also given.

Enantioselective Conia-Ene-Type Cyclizations of Alkynyl Ketones through Cooperative Action of B(C6F5)3, N-Alkylamine and a Zn-Based Catalyst

An efficient and highly enantioselective Conia-ene-type process has been developed. Reactions are catalyzed by a combination of B(C6F5)3, an N-alkylamine and a BOX-ZnI2 complex. Specifically, through cooperative

Cu-Catalyzed Tandem Aerobic Oxidative Cyclization for the Synthesis of 3,3′-Bipyrroles from the Homopropargylic Amines

A Cu-catalyzed method for the synthesis of 3,3′-bipyrroles from homopropargylic amines through tandem aerobic oxidative cyclization involving the formation of C-C bond has been developed. The features of this reaction are a small number of Cu catalysis and simple starting substrates. Moreover, this procedure exhibits good functional group tolerance and a series of 3,3′-bipyrroles derivatives are obtained in moderate to good yields.
