By Using cyclopentadiene and carbon=carbon bond compounds as raw materials,based on Diels-Alder reaction,norbornene derivatives were prepared,such as 5-phenyl-2-nobornene,5-cyano-2-nobornene,5-carboxyl-2-nobornene and 5-nobornene-2-hydroxybutyrate.

• 本文研究了以环戊二烯和其它含有碳碳双键的化合物为原料,通过Diels-Alder反应,合成了降冰片烯类化合物:5-苯基-2-降冰片烯、5-腈基-2-降冰片烯、5-羧基-2-降冰片烯。
