Abstract


This article describes three types of asymmetric Diels-Alder reaction . Nano solid superacid catalytic synthesis bornyl reaction (meth) acrylate and ( meth) acrylate and cyclopentadiene Diels-Alder reaction stereoselectivity problem . Nano solid superacid catalyzed , borneol with (meth ) acrylic acid esterification reaction can be carried out smoothly . The effects of reaction time , reaction temperature , acid molar ratio , catalyst dosage on the esterification reaction , thus deriving the optimal reaction conditions of the esterification reaction 2 the > O 8 < / sub > 2 - / ZrO 2 < / sub > reuse and activation of the regeneration of the inspection . And the product of the boiling point , IR , 1H NMR , 13C NMR and other tests . Thesis natural dextrose bornyl acrylate as a chiral auxiliary to give the chiral , the ester with cyclopentadiene , followed by hydrolysis to give the corresponding acid and alcohol, in the asymmetric Diels-Alder reaction to different temperatures was investigated . factors such as the presence or absence of catalyst on the Diels-Alder reaction . Stereoselective thesis methacrylate with cyclopentadiene Diels-Alder reaction . Investigated under different conditions, the yield of the reaction and the proportion of internal and external type , the possible reasons for the addition of a catalyst to change the product inside and outside type proportion and initially speculated .
