Abstract

... di- hydropyridinium salts 2 (Scheme I). These compounds are potentially powerful synthons for the preparation of functionalized piperidines as one can envisage successive control over three of the ring carbon centers (C-2,3,4). However, the chemistry of this ... J. Org. Chem., Vol. ...
