Abstract

A great number of piperidine-containing compounds are biologically and medicinally interesting. 1., , , and As a consequence, the development of general methods for the synthesis of piperidine derivatives has been the subject of considerable synthetic efforts. 2 The addition of stabilized anions 3., , and and organocuprates 4., and to γ-substituted α,β-unsaturated δ-lactams 1 has been used as a method for the stereoselective synthesis of cis- and trans-3,4- ...
