Abstract: Abstract 5-bromosalicylaldehyde (1) was reacted with thiosemicarbazide to afford thiosemicarbazone derivative 2. The latter underwent cyclocondensation upon reaction with α-haloester, α-haloketone as well as hydrazonoyl halides affording 1,3-thiazoles and arylazothiazoles 3-6, respectively. On the other… read more here.
