摘要

Taking into consideration the previous work on SmI 2 -promoted intramolecular cyclisations of ketyl-hydrazones 13 or ketyl-oximes 14 for the formation of five-, six- and seven-membered cyclic amino alcohols, initial efforts were focused on the ability of a nitrone group to undergo intramolecular coupling with either a hydrazone or oxime. Hence, the nitrone hydrazone 1 was first submitted to conditions reported by Sturino and Fallis 13a for promoting ring formation (SmI 2 2.4 ...
