The present invention pertains generally to the field of chemical synthesis, and more particularly to methods for the chemical synthesis of a thiosulfonic acid of Formula (1) by a step of periodate mediated oxidative coupling of a thiosulfonic acid of Formula (2) with an aniline of Formula (3), as described herein. The present invention also relates to such methods which incorporate one or more additional (subsequent and/or preceding) steps, for example, to prepare compounds of Formula (5) from compounds of Formula (1); to prepare compounds of Formula (6) from compounds of Formula (5); and to prepare compounds of Formula (2) from compounds of Formula (4), as described herein.
本发明一般涉及化学合成领域,更具体地涉及一种通过亚硫酸酯类化合物(化学式(2))与苯胺(化学式(3))的间碘酸盐介导氧化偶联的步骤来化学合成一种亚硫酸硫酸的方法(化学式(1)),如本文所述。本发明还涉及这种方法中包括一个或多个额外的(随后和/或先行的)步骤,例如,从化合物(化学式(1))制备化合物(化学式(5));从化合物(化学式(5))制备化合物(化学式(6));从化合物(化学式(4))制备化合物(化学式(2)),如本文所述。
