Abstract

Herein we report the formation of pyrrolines and tetrahydropyridines from the cyclisation reactions of β-amino allenes by both Au^I and Ag^I catalysts in yields ranging from 5 to 70 %. Au^I catalysts favour a 5-endo-dig cyclisation before rapid rearrangement to the 5-exo-dig product, while Ag^I favours a 6-endo-trig cyclisation. We also report the first known Ag₂O catalysed cyclisation reaction of an allene which occurred in good yield (61 %).
