Abstract

The search for configurationally stable alpha-amino carbanions has led to an interesting observation of differing reactivity of diastereomeric organolithiums and to the characterization of aracemic 2-lithio-N-methylpiperidine and 2-lithio-N-methylpyrrolidine as configurationallystable alpha-aminoorganolithiums. Details for the preparation of these and related alpha-lithioheterocycles, evaluation of their chemical and configurational stability, and a preliminary evaluation of the stereoselectivity of their reactions with electrophiles is presented.
