Ultrasound-assisted synthesis of functionalized 1,3-enynes by palladium-catalyzed cross-coupling reaction of alpha-styrylbutyltelluride with alkynyltrifluoroborate salts
(GEORG THIEME VERLAG KG, 2008)
An ultrasound-assisted synthesis of functionalized 1,3-enyne scaffolds is described and illustrated by palladium-catalyzed cross-coupling of potassium alkynyltrifluoroborate salts and alpha-styrylbutyltellurides. This ...
Crystal structures and biological activity of 1,1,4-triphenyl-substituted 1,3-enyne compounds
(2019)
1,3-Enyne structural motifs are versatile building blocks in organic synthesis and
occur widely in various natural products with many of them being highly active
as cytotoxic macrolides and antitumour antibiotics. This ...
One-Pot Conversion of Aldehydes and Ketones into 1-Substituted and 1,4-Disubstituted 1,3-Enynes
(2018)
Sequential treatment of 2,3-dichloropropene with magnesium and n-BuLi generates the operational equivalent of 1,3-dilithiopropyne, which upon treatment with aldehydes or ketones, produces the corresponding alkoxy lithium ...
Synthesis of (Z)-tributylstannyl enynes: systematic studies of Sonogashira cross-coupling reactions between (E)-1-iodovinyl-1-tributylstannanes and terminal acetylenes using amines or tetrabutylammonium hydroxide (TBAOH) as activator
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Sonogashira cross-coupling reactions involving (E)-iodo vinyl stannanes and terminal acetylenes were carried out in the presence of Pd(PPh(3))(4), Cul and several amines, affording (Z)-tributylstannyl enynes in moderate ...
Synthesis and preliminary determination of antibacterial activity of some 1,3-enynes
(2019)
The synthesis of five 1,3-enynes was performed and its activity against Gram-positive and Gram-negative bacteria was determined.
Coupling of vinylic tellurides with alkynes catalyzed by palladium dichloride: Evaluation of synthetic and mechanistic details

Binding of molecular magnesium hydrides to a zirconocene-enyne template
(Wiley-VCH VerlagWeinheim, 2012-08)
An enyne-zirconium complex stabilizes molecular magnesium hydride ('MG''H IND. 2') and even a molecular hydride, n'C IND. 4''H IND. 9''MG'H. These systems feature magnesium olefin "pi" complexation.
Electrophilic addition of Propargylic cations to allenes: formation of crowded Chloro- and Azido-Enynes by trapping of the resulting allylic cations with TMSX (X = Cl, N3): a synthetic and computational study
(Wiley VCH Verlag, 2013-07)
Propargylic cations, generated by the ionization of propargyl alcohols with catalytic amounts of Bi(OTf)3, react with arylsubstituted allenes to generate incipient allylic cations that are quenched in the presence of TMSCl ...
Creation of quaternary stereocenters by the addition of allyltributyltin to chiral cyclic N-acyliminium ions
(Pergamon-elsevier Science LtdOxfordInglaterra, 2000)
Design of a Selective Ring-Closing Enyne Metathesis-Reduction for the Generation of Different Synthetic Scaffolds
(American Chemical Society, 2018-10)
A tandem process of ring-closing enyne metathesis (RCEYM)-reduction using modern ruthenium catalysts and a hydrogen donor is described. This straightforward methodology is useful for C(sp3) generation under mild reaction ...
