A practical asymmetric synthesis of 2,6-cis-disubstituted piperidines
摘要:
A highly diastereoselective intramolecular Mannich reaction involving enantiopure alpha-methylamine 7 and achiral aldehydes is employed to prepare enantiomerically pure 2,6-cis-disubstituted piperidines. This methodology provides an efficient and selective route to 2,6-cis-disubstituted piperidines, 2,6-cis-disubstituted 4-piperidones and 2,6-cis-disubstituted 4-piperidinols.
