Stereo- and regiocontrolled construction of trisubstituted piperidines using a TpMo(CO)(2)(dihydropyridine) scaffold (Tp = hydridotrispyrazolylborate).

A F Moretto1, L S Liebeskind.   

Abstract

Cationic TpMo(CO)(2)(dihydropyridine) complexes (Tp = hydridotrispyrazolylborate), readily generated from 3-oxo-3, 6-dihydro-2H-pyridine-1-carboxylic acid benzyl ester, represent scaffolds from which (by judicious choice of demetalation conditions) either 2,3,6- or 2,5,6-trisubstituted-1,2,3, 6-tetrahydropyridines can be prepared in a regio- and stereodefined way.
