We also prepared some other macrocyclic enones by the use of the same synthetic procedure (Table 3, entry 5); (E)-cycloicos-2-enone (y. 98%), (E)-cyclohexadec-2-enone (y. 98%), (E)-cyclotridec-2-enone (y. 66%), and (E)-cyclododec-2-enone (y. 38%). Elimination reactions of less than 10-membered ring mesylates did not proceed, probably due to a highly labile cyclopropyl cationic intermediate.

Recently Tanabe and co-workers reported similar reaction mechanism of ammonium sulfonates promoted elimination of 7b or 7c. They have noted that the elimination reaction is considered to proceed through the cyclopropyl cationic intermediates, that is, via the 1,3-elimination pathway. Uchimura, D.; Funatomi, T.; Tanabe, Y.
