Synthetic routes to all four diastereoisomers of 3-thymine-1-(tbutoxycarbonyl)aminocyclopentane-1-carboxylic acid have been developed starting from the commercially available (S)-dimethyl malate. The key step in the synthesis involves dialkylation of N-(diphenylmethylene)glycine ethyl ester with 1,4-diiodo-2(S)-trityloxybutane.
