7-Oxanorbornene derivatives functionalized with alkyneappendages undergo intramolecular enyne metathesis reactions to give cis-fused 2,6-dioxabicyclo[4.3.0]nonane derivatives. These compounds have a diene functionality thatallows their reaction with dienophiles (N-phenylmaleimide) to yield densely functionalized polycyclic compounds. (© Wiley-VCH Verlag GmbH & Co.

用炔烃附属物官能化的 7-氧代降冰片烯衍生物进行分子内烯炔复分解反应,得到顺式稠合的 2,6-二氧杂双环 [4.3.0] 壬烷衍生物。这些化合物具有二烯官能团,允许它们与亲二烯体(N-苯基马来酰亚胺)反应以产生密集官能化的多环化合物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
