The first asymmetric synthesis of (trifluoromethyl)pipecolic acids is reported. The synthetic strategy involves as key step an intramolecular Mannich reaction of a homochiral α-Tfm-β-amino ketal, prepared with a high stereoselectively in four steps

The highly diastereoselective synthesis of five trifluoro-substituted analogues of mono-, di-, and trisubstituted piperidine alkaloids was accomplished in two to four steps from 2-trifluoromethyl keto-protected 4-piperidones, prepared by an intramole

An intramolecular Mannich-type reaction, involving either an a-trifluoromethyl-l,3-aminoketal or a fluoral synthetic equivalent, was employed to prepare diastereoselectively α-trifluoromethylpiperidines. This simple strategy allows a facile access t

The asymmetric synthesis of α-chiral 1,3-aminoketals 1 , useful chiral building blocks for piperidine preparation, was achieved in seven steps involving highly diastereoselective 1,4-addition of Davies’ lithium amide to an α,β-unsaturated ester.
