Depending on their N-substitution pattern the aziridination can afford trans- or cis-aziridines preferentially. — (OCHIAI, M.; KITAGAWA, Y.; Tetrahedron Lett. 39 (1998) 31, 5569-5570; Fac. Pharm.

42 - 112Reaction of Monocarbonyl Iodonium Ylides with Activated Imines:Stereoselective Synthesis of trans- and cis-α,β-Aziridino Ketones. —Treatment of iodonium salts (I) with lithium ethoxylate generates monocarbonyliodonium ylides which readily undergo alkylidene-transfer reactions with acti-vated imines. Depending on their N-substitution pattern the aziridination canafford trans- or cis-aziridines preferentially. — (OCHIAI, M.; KITAGAWA,Y.; Tetrahedron Lett. 39 (1998) 31, 5569-5570; Fac. Pharm.
