| Abstract: | Two methods utilized in the synthesis of [9](2,4)pyrrolophanes are reported. The first, an application of the Paal-Knorr cyclization, involved the condensation of ammonia with 3-formylcyclododecanone. The second method employed the condensation of 3-chlorocyclododec-2-en-1-one with diethyl aminomalonate. |
