与富烯和各种烯烃的Diels-Alder反应不同，6-氨基富烯与马来酸酐（或马来酰亚胺）反应生成[6 + 2]环加成物，构成了合成并环戊二烯并[1，2-c]呋喃、并环戊二烯并[1，2-c]吡咯和环戊二烯并[a]并环戊二烯骨架的一条有效的新途径。
In contrast to the Diels-Alder reaction of fulvenes and various alkenes, 6-aminofulvenes react with maleic anhydride (or maleimide) to give [6 + 2] cycloaddition adducts, constituting an efficient and novel route to pentaleno[1,2-c]furan, pentaleno[1,2-c]pyrrole, and cyclopenta[a]-pentalene skeleton.
