Three new classes of atropisomeric compounds, that is, 6-aryl-dihydro-pyridin-2-ones, 6-aryl-pyridin-2-ones and 2-aryl-pyrroles, have been prepared from chiral imines through an efficient stereoselective tandem Michael-azacyclization process. In all cases, a study has shown that the barrier to rotation of the chiral axis is remarkably high. (C) 2003 Elsevier Ltd. All rights reserved.
