Abstract
A new tricyclic ring system, dibenz[b, g][1, 5]oxazocine derivatives (VIII), was synthesized. In this reaction, a 16-membered ring compound (IX) was obtained as a byproduct besides the objective VIII, and formation ratio of these two compounds varied with reaction conditions. Catalytic reduction of the 6-benzyl compound (VIII-5) gave 6, 7-dihydro-5H-dibenz[b, g][1, 5]oxazocine (X) and various derivatives of X were prepared. 6-(ω-Alkylaminoalkyl)-6, 7-dihydro-5H-dibenz[b, g][1, 5]oxazocines (XXVI) and 5, 13-bis(ω-dialkylaminoalkyl)-2, 3-, 7, 8-, 10, 11-, 15, 16-tetrabenzo-1, 9-dioxa-5, 13-diazacyclohexadeca-2, 7, 10, 15-tetraenes (XXVII) were synthesized.
