Le. Burgess et al., THE PREPARATION OF ALPHA-SUBSTITUTED, BETA-HYDROXY PIPERIDINES AND PYRROLIDINES - THE TOTAL SYNTHESIS OF FEBRIFUGINE, Tetrahedron letters, 37(19), 1996, pp. 3255-3258
Epoxides generated from cyclic ene carbamates are effective N-acyl imi
nium ion precursor and allow for the preparation of beta-hydroxy, alph
a-substituted piperidines and pyrrolidines. The total synthesis of rac
emic Febrifugine is also described. (C) 1996 Elsevier Science Ltd.
