Norbornadienes and 7-heteronorbornadienes are reacted with 7-oxa (or carba or aza) norbornenefused cyclobutene epoxides (or aziridines) to produce hetero-bridged polynorbornane cycloadducts containing syn-facially arranged N,O (or C,N or C,O) bridges. New dual cyclobutene epoxides and dual cyclobute
