Efficient routes to the synthesis of norbornadiene-tethered nitrileoxides have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in good yields for a variety of substrates and were found to be highly regio- and stereoselective, giving single regio- and stereoisomers in most cases.
A comparative study of the Diels-Alderreaction have been carried out for three types of cyclic dienes: cyclopentadiene (CPD), hexachlorocyclopentadiene (HCP), and tetrachloro-1,2-benzoquinone (TCBQ) with dienophiles of five types: monosubstituted acetylenes (propargyl alcohol and its esters), conjugated amines (allyl acetylene, allyl ethynyldimethylcarbonol and its esters), conjugated dienes (2-methylhexadiene-3
已对三种类型的环状二烯进行Diels-Alder反应的比较研究:环戊二烯(CPD),六氯环戊二烯(HCP)和四氯-1,2-苯醌(TCBQ)与五种亲二烯体:单取代乙炔(炔丙醇及其酯),共轭胺(烯丙基乙炔,烯丙基乙炔基二甲基碳醇及其酯),共轭二烯(2-甲基己二烯-3,5-ol-2及其酯,1-乙氧基和1-乙氧基羰基丁二烯-1,3 )和共轭三烯(hexatriene-1,3,5 and 5-methylhexatriene-1,3,5)。

Efficient routes to the synthesis of norbornadiene-tethered nitrones have been developed, and their intramolecular 1,3-dipolar cycloadditions were studied. The cycloadditions occurred in moderate to good yields for a variety of substrates and were found to be highly regio- and stereoselective, giving single regio- and stereoisomers in most cases.
