-
Page/Page column 3, (2015/02/18)
Surfactants and solvents containing derivatized adducts formed from Diels-Alder reactions of terpenes and unsaturated carboxylic acids or their derivatives are disclosed. Processes for making and derivatizing the Diels-Alder adducts are also disclosed.
Preparation of ecological catalysts derived from Zn hyperaccumulating plants and their catalytic activity in Diels-Alder reaction
Escande, Vincent,Olszewski, Tomasz K.,Grison, Claude
, p. 731 - 737 (2014/07/21)
Zn hyperaccumulating plants Noccaea caerulescens and Anthyllis vulneraria were used as the starting material for preparation of novel Lewis ecological catalysts. Those catalysts efficiently mediate the Diels-Alder reaction. High yields, very good regio- a
Ruthenium-catalysed codimerisation of myrcene with methyl acrylate: Catalyst screening and mechanistic discussions
Behr, Arno,Johnen, Leif,Rentmeister, Nils
, p. 204 - 212 (2013/04/10)
The codimerisation of 1,3-dienes and acrylic compounds is a feasible strategy for the synthesis of functionalised alkenes. In this work, a direct approach to novel C13 esters for the flavour and fragrance industry was performed by codimerisatio
High regioselective Diels-Alder reaction of myrcene with acrolein catalyzed by zinc-containing ionic liquids
Yin, Donghong,Li, Changzhi,Li, Biaomo,Tao, Liang,Yin, Dulin
, p. 137 - 142 (2007/10/03)
The ambient zinc-containing ionic liquids, MX-ZnCl2, functioning as both Lewis acid catalyst and green solvent, are employed for a high regioselective Diels-Alder reaction of myrcene with acrolein for the first time, where MX is either 1-butyl-3-methylimidazolium chloride (BmimCl), 1-ethyl-3-methylimidazolium bromide (EmimBr), N-butylpyridinium bromide (BPyBr), or N-ethylpyridinium bromide (EtPyBr). Compared with the analogous reaction performed over a ZnCl2 catalyst in the conventional solvent dichloromethane, higher regioselectivity of the 'para' cycloadduct and excellent yield were achieved at shorter reaction time in these ionic liquids with optimized molar compositions of MX and ZnCl2. These moisture-insensitive ionic liquids can be easily separated from reaction products after simple washing with hexane, allowing their reuse with no obvious loss in activity.

Oskooie, Hossein Abdi
, p. 1165 - 1167 (2007/10/03)
Diels-Alder reactions of myrcene (7-methyl-3-methene-1,6-octadiene) with carbonyl containing dienophiles supported on silica gel under microwave irradiation have been studied.
Nanoporous solid acid catalyst for the Diels-Alder reaction of 1,3-dienes with acrylates
Onaka, Makoto,Hashimoto, Naoki,Yamasaki, Ryota,Kitabata, Yasuyoshi
, p. 166 - 167 (2007/10/03)
Nanoporous aluminosilicate, Al-HMS with a high aluminum content, strong acidity, and nanoporosity was found to catalyze the Diels-Alder reaction of 1,3-dienes with methacrylate and acrylate, and turned out to be a green alternative to homogeneous acid catalysts.
DRAMATIC ACCELERATION OF THE DIELS-ALDER REACTION BY ADSORPTION ON CHROMATOGRAPHY ADSORBENTS
Veselovsky, V. V.,Gybin, A. S.,Lozanova, A. V.,Moiseenkov, A. M.,Smit, W. A.,Caple, R.
, p. 175 - 178 (2007/10/02)
The development of a new method for effecting cycloadditions on the surface of chromatographic adsorbents in the absence of solvents that leads to a moderation of the reaction conditions and an increase in selectivity is described.
Synthesis of p-Camphorene
Vig, O. P.,Kad, G. L.
, p. 507 - 509 (2007/10/02)
p-Camphorene is synthesised by the application of Wittig reaction with methylenetriphenylphosphorane on 1(4-methyl-3-pentenyl)-4-(5-methyl-4-hexe-1-one)cyclohex-1-ene (5), the cardinal intermediate, which was procured by the formation of β-ketosulphoxide and then its subsequent alkylation with 1-bromo-3-methyl-2-butene of the compound 1(4-methyl-3-pentenyl)-4-carbmethoxycyclohex-1-ene (3).The alkylated material was submitted to reductive cleavage with aluminium amalgam in aqueous THF at 65 deg to furnish 5.
LINEAR CODIMERIZATION OF MYRCENE WITH METHYL ACRYLATE AT COMPLEX COBALT CATALYSTS
Zakharkin, L. I.,Petrushkina, E. A.
, p. 441 - 443 (2007/10/02)
During the codimerization of myrcene with methyl acrylate at complex cobalt catalysts a mixture of four linear codimers is formed, i.e., methyl 5-ethylidene-9-methyl-(E)-2,8- and 5-ethylidene-9-methyl-(Z)-2,8-decadienoates and methyl 6,10-dimethyl-(E)-2,5,9- and 6,10-dimethyl-(Z)-2,5,9-undecatrienoates.
