Photoinduced Decarboxylative Phosphorothiolation of N-Hydroxyphthalimide Esters

A visible-light-induced protocol for the synthesis of phosphorothioates is developed by employing the Ir-catalyzed decarboxylative phosphorothiolation of N-hydroxyphthalimide esters. This novel synthesis method utilizes carboxylic acids as raw material, which is stable, cheap, and commercially available. Scope studies show that this reaction has good compatibility of functional groups. Notably, both the synthesis of steric hindrance phosphorothioates and the later modification of some bioactive compounds are successfully achieved.

Reaction of N-(Cyclohexylthio)phthalimide with Phosphorus Acids

Reaction of N-(cyclohexylthio)phthalimide with phosphorous and dithiophosphoric acid esters yields phthalimide, its alkyl derivatives, and S-cyclohexyl thio- and trithiophosphates.
