Abstract

A novel organoruthenium(iii) amidinate, (η5-C5Me5)RuCl(η-iPrN=C(Me)NiPr) (2), has been prepared by oxidation of organoruthenium amidinate, (η5-C5Me5)Ru(η-iPrN=C(Me)NiPr) (1), by organic chlorides; both 1 and 2 are found to be good catalysts for atom-transfer cyclization of N-allyltrichloroacetamides which are useful for successful preparation of a pyrrolizidine alkaloid skeleton under mild conditions.
