Enantiomerically pure (R)- or (S)-1,1-dialkoxy-2-propanamines 5 are obtained in good chemical and optical yields, by asymmetric reduction of chiral imines prepared from 1,1-dialkoxy-2-propanones, using (R)- or (S)-1-phenylethylamine ((R)- or (S)-2) as an inexpensive, efficient chiral auxiliary.

Based on anti-viral screening of our heteroaromatics derived from thalidomide, the gamma-carboline skeleton has been identified as a superior scaffold structure for compounds with potent anti-bovine viral diarrhea virus (BVDV) activity. Structural development studies led to a potent anti-viral agent, SK5M (5-methyl-gamma-carboline), with the EC50 of 0.26 mu M. (C) 2008 Elsevier Ltd. All rights reserved.
