摘要:
A novel beta-amino acid having (thymin-1-yl)methyl functionality at the alpha-position, a useful component of alpha-substituted beta-homoalanyl peptide nucleic acids (beta(2)-PNAs), was synthesized as a protected form from 2-(N-3-benzoylthymin-1-yl)methyl-1,3-propanediol via enzymatic desymmetrization catalyzed by lipase PS.
