Abstract

In this paper, Michael addition reaction is carried out by treating 3,3-dimethyl-2,6-diarylpiperidin-4-ones (1a-c) with methyl vinyl ketone in the presence of sodium ethoxide. The products 2a-c and 3a-c formed are analyzed by UV, IR, ¹H NMR and ¹³C NMR spectral methods. In all the cases, the ¹H NMR studies confirm the trans- ring fusion.
