, 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

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

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.
Diels-Alder reaction of myrcene with carbonyl containing dienophiles supported on silica gel under microwave irradiation

, 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.
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.
