A novel approach to the synthesis of substituted 5-amino- and 3-amino-1,2,4-thiadiazoles beginning from a common precursor has been achieved. Derivatization by palladium-catalyzed Suzuki−Miyaura coupling enables the rapid preparation of analogs around this pharmaceutically relevant core. FMO calculations rationalize the observed chemoselectivity for coupling at chlorine.
