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.

of functionalized macrocyclic ketones has been developed. Pyrolysis of medium- and large-ring 3-vinylcycloalkanones by dynamic gas-phase thermo-isomerization (DGPTI) at 600–630° yielded, under insertion of a previously attached vinyl side chain by means of a 1,3-C shift, the corresponding γ,δ-unsaturated cycloalkanones. The yield of the two-carbon ring-expanded ketones greatly depended on the relative
