Abstract :

Spirocyclization of keto-ynamides with quaternary ammonium salts was performed to access aza-spiro compounds. Exclusive E-configured 5-exo-dig compounds were isolated from keto-ynamides substituted by an aryl- or a vinyl group, whereas 6-endo-dig compounds were favored from terminal ynamides.
