Substituted Aziridines by Lithiation—Electrophile Trapping of Terminal Aziri— A new, experimentally straightforward method for the stereocontrolled for30- 086 dines.
mation of α,β-aziridinylsilanes by aziridine lithiation—in situ silylation is developed.
(I) is deprotonated with a hindered lithium amide and subsequently trapped with a variety of electrophiles. The procedure is attractive because it proceeds directly from simple terminal aziridines to give trans-disubstituted aziridines. — (HODGSON*, D. M.;
