Objective To prepare R-（＋）-thiotetrahydrofunan-2-carboxylic acid. Method R-（＋）- thiotetrahydrofuran-2-carboxylic acid was synthesized from tetrahydrofuran-2-carboxylic acid via three steps： resolution, chlorination and displacement. Results The total yield was 29% and the structure of desired compound was confirmed by 1H-NMR and MS. Conclusions The new route for synthesis of R-（＋）-thiotetrahydrofuran-2-carboxylic acid is developed, and the process is easy to operate.
