Pyrrole derivatives
R 0120
Palladium-Mediated Arylation of 3-Aminopiperidines and 3-Aminopyrrolidines.
It is found that arylation of 1-protected 3-aminopiperidines and 3-aminopyrrolidines
19- 122 —
provides an effective approach to products of type (III), (V), and (VII) which are of
synthetic and biological interest. A right choice of ligand and temperature is necessary
to achieve high yields. Arylation of the unprotected derivatives predominantly gives
the undesired 1-substituted products. — (JEAN, L.; ROUDEN*, J.; MADDALUNO,
