Mj. Woltering et al., STEREOSELECTIVE SYNTHESIS OF HYDROXYLATED INDOLIZIDINES VIA (-)-SPARTEINE-MEDIATED KINETIC RESOLUTION COUPLED WITH INTRAMOLECULAR CARBOLITHIATION, Synlett, (7), 1998, pp. 797-800
Enantioenriched 1-oxy-2-benzyl-substituted indolizidines with function
alized side chains were easily prepared from racemic 2-(carbamoyloxy)m
ethyl-N-cinnamylpiperidine by (-)-sparteine-mediated one-step kinetic
resolution and intramolecular carbolithiation.
