Autor: Hovhannes S. Attaryan, G. G. Danagulyan, A. M. Arzumanyan, H. N. Khachatryan, A. G. Shahkhatuni

Publikováno v: Russian Journal of Organic Chemistry. 56:1488-1490

Commercial vinylacetic acid is a mixture of isomers of but-3-enoic and but-2-enoic acids. It was shown that but-3-enoic acid undergoes isomerization in the presence of a catalytic amount of 1-ethylpyrazole. The resulting Z- and E-isomers of but-2-eno

Publikováno v: Chemistry of Natural Compounds. 52:256-261

Vinyl-containing lupane- and oleanane-type C-3 and C-28 esters were synthesized from betulin and A-secotriterpene alcohols. The reaction of 2,3-secolupane alcohol 5 with vinylacetic acid produced ester 8 and a recyclization product, methyl 2β,3β-di

Synthesis of α-chiral-β,γ-unsaturated carboxylic acid derivatives using chiral auxiliaries

Autor: Bianca R. Sculimbrene, Victoria A. Lee, Kelsey E. Poremba

Publikováno v: Tetrahedron. 70:5463-5467

We report an efficient and reliable method for the synthesis of α-chiral-β,γ-unsaturated carboxylic acid derivatives using chiral auxiliaries and vinylacetic acid. Two well-established chiral auxiliaries ((S,S)-pseudoephedrine and (R)-benzyl-oxazo

Synthesis of Novel 2-Oxoquinoline Derivatives via Ugi-Four-Component-Heck Reaction

Autor: Mina Saeedi, Mohammad Ali Rasouli, Parviz Rashidi Ranjbar, Mohammad Mahdavi, Alireza Foroumadi, Abbas Shafiee

Publikováno v: Journal of Heterocyclic Chemistry. 52:386-391

The present study provides an efficient strategy for the preparation of novel N-substituted-4-methyl-quinolin-1(2H)-one derivatives via two-step Ugi/Heck reaction. The procedure is based on the Ugi coupling between 2-bromoanilines, various aromatic a

ChemInform Abstract: Synthesis of Novel 2-Oxoquinoline Derivatives via Ugi-Four-Component-Heck Reaction

Autor: Mohammad Mahdavi, Mina Saeedi, Alireza Foroumadi, Mohammad Ali Rasouli, Parviz Rashidi Ranjbar, Abbas Shafiee

Publikováno v: ChemInform. 46

Ugi coupling of 2-bromoanilines with aromatic aldehydes, vinylacetic acid, and isocyanides followed by intramolecular Heck reaction of the Ugi adducts (V) provides the title compounds (VI) (11 examples) in good yield.

Synthesis of BEDT-TTF derivatives with carboxylic ester and amide functionalities

Autor: R.James Brown, Gemma Camarasa, Peter Day, John D. Wallis, Jon-Paul Griffiths

Publikováno v: Tetrahedron Letters. 45:5103-5107

Synthetic routes to BEDT-TTF derivatives bearing side chain carboxylic ester and amide groups are reported. Methyl ET-ethanoate was prepared in five steps from vinylacetic acid; amide groups were installed early in the synthesis by mixed anhydride me
