The total synthesis of (±)-3-thiaglutamate is reported. Central to our strategy is an thiol addition to an imine to form the thioaminal of the natural product. The resulting thioaminal product is then subjected to triflic acid global deprotection to produce 3-thiaglutamate as a triflate salt. This work constitutes the first total synthesis of 3-thiaglutamate and demonstrates that the hemithioaminal group in 3-thiaglutamate can be stabilized under acidic conditions.
