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.
报道了在[9](2,4)吡咯烷酮的合成中使用的两种方法。第一个是Paal-Knorr环化的应用,涉及氨与3-甲酰基环十二烷酮的缩合。第二种方法是将3-氯环十二烷基-2-烯-1-酮与氨基丙二酸二乙酯缩合。
