Access to Fully Substituted Thiazoles and 2,3-Dihydrothiazoles via Copper-Catalyzed [4 + 1] Heterocyclization of α-(N-Hydroxy/aryl)imino-β-oxodithioesters with α-Diazocarbonyls.

Journal of Organic Chemistry, 2017
An efficient chemoselective practical route to fully substituted thiazoles and 2,3-dihydrothiazoles has been devised by [4 + 1] heterocyclization of α-(N-hydroxy/aryl)imino-β-oxodithioesters with in situ generated Cu-carbenoids of diazocarbonyls.

K2S2O8-Promoted Direct C–H Phosphorylation of (Benzo)thiazoles

, 2017
The direct phosphorylation of (benzo)thiazoles with various H-phosphine oxides was realized by using K2S2O8 as the oxidant. A series of 2-phosphoryl (benzo)thiazoles were obtained in moderate to good yields.
