摘要

A practical synthetic entry to Wenkert's enamine 1 employing the modified Polonovski reaction is described. Complete 13C NMR spectral data of 1 is presented. Conformational analysis of the intermediate 1-hydroxy-and 1-ethyl-1-hydroxy-indoloquinolizidines 20a, 20b, 21a and 21b based on simple but reliable 13C NMR spectral correlations is presented.
