Telluro-directed regiospecific and highly stereoselective reaction of ethyl 5-telluro-(2E,4Z)-pentadienoate with organocopper reagents

Ethyl 5-telluro-(2E,4Z)-pentadienoate 2, which is prepared by the Wittig olefination of (Z)-β-telluroacrolein 1, reacted very rapidly with organocuprates 3 at -78°C to form exclusively the corresponding 5-substituted products 4 with high stereoselectivity

Isomerization of electron-poor alkynes to the corresponding (E, E)-1,3-dienes using a bifunctional polymeric catalyst bearing triphenylphosphine and phenol groups

The use of a bifunctional non-cross-linked polystyrene bearing both phosphine and phenol groups for the organocatalytic isomerization of alkynes bearing electron-withdrawing ester substituents to afford the corresponding (E,E)-dienes in excellent yield an

Highly stereoselective and efficient synthesis of ω-heterofunctional di- and trienoic esters for Horner-Wadsworth-Emmons reaction via alkyne hydrozirconation and Pd-catalyzed alkenylation

In situ OH metalation with iBu2AlH and hydrozirconation with HZrCp2Cl of HOCH2C{triple bond, long}CH, (E)-HOCH2CH{double bond, long}CHC{triple bond, long}CH, and HOCH2C{triple bond, long}CC

Stereoselective synthesis of naturally-occurring 7-(hetero)aryl (2E,4E,6E)-2,4,6-heptatrienamides and their structural analogues

A new and efficient highly stereoselective method to prepare naturally-occurring 7-(hetero)aryl (2E,4E,6E)-2,4,6-heptatrienamides and their structural analogues has been developed. The physical and spectral properties of one of these compounds, i.e. (2E,4E,6E)-7-(2-thienyl)-2,4,6-heptatrienoic acid piperidide (4b), have been found to be quite different from those previously reported for 7-(-2-thienyl)-2,4,6,-heptatrienoic acid piperidide isolated from Othantus maritimus to which the (2E,4E,6E)-configuration had been previously assigned.

Palladium-Catalyzed Syntheses of Conjugated Trienes

Conjugated trienes 3 and 5 have been prepared by the palladium-catalyzed reaction of alkenes 2 with fumaryl chloride (1) and (E)-5-phenyl-2,4-pentadienoyl chloride (4), respectively, in the presence of N-ethylmorpholine.
