3-fused polycyclic cyclopropenes, 10, 11, and 12. The stereochemistry of the Diels-Alder reactions of cyclopropene 16 with furan and DPIBF are different. Cyclopropene 16 was treated with furan to form exo-exo and endo-exo adducts (5:2) and treated with DPIBF to generate an exo-exo adduct. Compounds 10, 11 and 12 undergo isomerization reactions to form benzaldehyde and phenyl 4-phenyl-[1]naphthyl ketone
三个 1,3-桥接多环环丙烯、exo-8-oxatricyclo[3.2.1.0 2 , 4 ]octa-2,6-diene (10)、endo-8-oxatricyclo[3.2.1.0 2 , 4 ]octa-2,通过消除2-chloro-3-trimethylsilyl-8-oxatricyclo[3.2.1.0 2 , 4 ]-oct-6-enes, 17, 18 and 30, 由 1-chloro-3-trimethylsilylcyclopropene 与呋喃和二苯基异苯并呋喃生成。我们已经证明了一种合成高应变 1,3-稠合多环环丙烯、10、11 和 12 的简便途径。环丙烯 16 与呋喃和 DPIBF 的 Diels-Alder 反应的立体化学是不同的。环丙烯 16 用呋喃处理以形成外-外和内-外加合物 (5:2),并用 DPIBF 处理以产生外-外加合物。化合物 10,
