Two ringenlargement reactions are used to transform the alicyclic 8-membered allyl 2-oxocyclooctane-1-carboxylate (11) to the 13-membered 10-aza-[11]-(2,3)-thiophenophane-1,9-dione (17). The first step yielded the macrocyclic imide allyl N-(3-thienylmethyl)-2,10-dioxo-1-azacyclodecane-3-carboxylate (15) and, after deprotection, N-(3-thienylmethyl)-1-azacyclodecane-2,10-dione (16). In the second step

Synthesis of Macrocyclic<i>N</i>-Unsubstituted Imides

A synthetic method for the preparation of the hitherto unreported N-unsubstituted cycloalkanedicarboxamides from cycloalkanones is presented here. The methodology involves a two-atom ring expansion followed by N-deallylation under mild conditions to give the product in high yield.
