Abstract

A series of both enantiomers of chiral β-amino acid ester derivatives containing a 4-(piperidin-1-yl)pyrimidine moiety was prepared in high yield and excellent enantioselectivity excess (up to >99% enantiomeric excess) using a chiral cinchona alkaloid thiourea catalyst under one-pot solvent-free conditions. Antiviral bioassay experimental results showed that some of the chiral products exhibited higher antiviral activities against tobacco mosaic virus (TMV) in vivo than the commercial antiviral agent ningnanmycin.
