(2S,5R)-5-(4-Amino-2-oxopyrimidin-1(2H)-yl)-1,3-oxathiolane-2-carboxylic Acid is an intermediate for the synthesis of rac-cis-Lamivudine Acid (1R,2S,5R)-5-Methyl-2-isopropylcyclohexyl Ester (L172450), which is a protected impurity of the anti-viral Lamivudine (L172500).

1,5-Anhydro-2,3,4-trideoxy-2-[[(1,1-dimethylethoxy)carbonyl]amino]-D-erythrohexitol acts as a reagent in the preparation of topoisomerase inhibitors with potent anti-gram-positive activity. Used in the formation of dipeptide isoteres.

(2S,5R)-5-(Boc-amino)tetrahydropyran-2-carboxylic Acid (CAS# 603130-13-8) is aids in the synthesis of novel tetrahydropyran-based, topoisomerase inhibitors with anti-gram-positive activity. Also used in the synthesis of novel tetrahydropyran-based dipeptide isoster compounds.
