search for configurationallystable α-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 α-aminoorganolithiums. Details for the preparation of these and related α-lithioheterocycles, evaluation of their chemical and configurational
