Search for Configurationally Stable, Aracemic α-Amino Organolithiums
Gawley, Robert E.,Zhang, Qianhui
, p. 6077 - 6088 (1994)
The search for configurationally stable 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 configurationally stable α-aminoorganolithiums.Details for the preparation of these and related α-lithioheterocycles, evaluation of their and configurational stability, and a preliminary evaluation of the stereoselevtivity of their reactions with electrophiles is presented. - Keywords: α-Amino organolithiums; α-amino carbaions; 2-lithiopiperidine; 2-lithiopyrrrolidine; configurationally stable carbanions.
