The　electrochemical　preparation　of　2-aminothiazoles　has　been　achieved　by　the　reaction　of　active　methylene　ketones　with　thioureas　assisted　by　ᴅʟ-alanine　using　NH4I　as　a　redox　mediator.　The　electrochemical　protocol　proceeds　in　an　undivided　cell　equipped　with　graphite　plate　electrodes　under　constant　current　conditions.　Various　active　methylene　ketones,　including　13-keto　ester,　13-keto　amide,　13-keto　nitrile,　13-keto　sulfone　and　1,3-diketones,　can　be　converted　to　the　corresponding　2-aminothiazoles.　Mechanistically,　the　in　situ　generated　alpha-iodoketone　was　proposed　to　be　the　key　active　species.
