摘要

Site-selective 1,3-dipolar coupling at the norbornene #pi#-bond of 5,6-di-methylenenorbornene 1 yields cycloadducts with an end-fuesd 1,3-diene system which have been reacted with N=N(or C=C)dienophiles to produce ribbon molecules,in which the internal diazacyclohexene (or cyclohexene) subunits are capable of acting as conformational hinges.Direct coupling of 5,6-dimethylene- norbornene with 1,3,4-oxadiazoles or dual coupling with bis(cyclobutene epoxides) afforded bis(1,3-dienes) that diastereoselectively react with dienophiles to produce new,conformationally mobile,molecular tweezers.
