a wide variety of natural products, e. g. alkaloids, β-lactames, biotin, amino sugars has been synthesized by 1,3-dipolar cycloaddition reaction between nitrones and alkenes.
in this thesis, we have focused on the synthesis of highly substituted furan by the cycloaddition reaction of conjugated enynones with nitrones.
本论文是关于共轭烯炔酮与硝酮化合物反应生成多取代的呋喃化合物的研究,主要从三个方面进行了研究。
the cycloaddition reaction of dichlorocarbene with c60 has been studied by using the semi-empirical method am1. a reasonable mechanism of the reaction has been suggested.
