The present invention relates to a curable bicyclic compound derived from biomass, solvent-free curable composition and a method for preparing thereof. The curable compound derived from biomass according to the invention comprises a bicycle structure, to which one of two epoxide functional groups are bonded.
The kinetics of reversible (2+4)-cycloaddition of methyl acrylate to furan at 343.7 K

The current concentrations of the initial compounds and the products of the forward and back Diels-Alder reactions between furan and methyl acrylate were measured by the proton NMR method. The experimental data were approximated by spline functions to obtain the reaction time dependences of concentration ratios and their derivatives, which were used to calculate the rate constants for the formation and decomposition of the exo and endo adducts from the differential equations corresponding to the mechanism of the process, which excluded direct interconversions of the adducts. The rate constants for system movement to equilibrium from both sides experienced oscillations, probably, because of the existence of energy chains. Averaging by repeat spline approximation reduced these dependences to curves with a single minimum in the region of equilibrium concentrations, whereas the ratios between the rate constants for the forward and back reactions (equilibrium constants) remained virtually unchanged.

The scope of the Diels-Alder reaction catalyzed by bis(oxazoline) copper complexes has been investigated. In particular, [Cu((S,S)-t-Bu-box)](SbF6)2 (1b) has been shown to catalyze the Diels-Alder reaction between 3-propenoyl- 2-oxaz
Cationic bis(oxazoline)Cu(II) Lewis acid catalysts. Enantioselective furan Diels-Alder reaction in the synthesis of ent-shikimic acid
Evans, David A.,Barnes, David M.
, p. 57 - 58 (2007/10/03)
The highly enantioselective Diels-Alder reaction between acryloyl oxazolidinone and furan, catalyzed by cationic bis(4-tert-butyloxazoline)Cu)(II) complex 1, is presented. Though the reaction equilibrates rapidly at -20°C, reaction at -78°C permits isolation of the kinetic product mixture. The synthetic utility of the reaction is demonstrated by the conversion of the cycloadduct to ent-shikimic acid.
