Heterocyclic analogs of pleiadene. 73. Intramolecular cyclization of cinnamoyl- and o-chlorobenzoylperimidines
We have carried out the intramolecular cyclization of the anions of 4(9)- and 6(7)-cinnamoylperimidines and also of 4(9)-o-chorobenzoylperimidine. These partially hydrogenated pyrido- and quino[1,2,3-cd]perimidines were obtained for the first time. Their
