In order to examine the possible preference for anti or syn attack in bicyclic cyclobutenes, a series of heterocyclic bicyclohexenes, 3-8, has been subjected to the reaction towards 1,3-dipoles, particularly diazoalkanes.All dipolar cycloadditions

Heating the 3-azatricyclo2,5>heptanes (2) prepared from pyridine via 2-azabicyclohex-5-enes (1) results in ring opening to give the corresponding 1,4-dihetero seven-membered ring compounds (3).
