A selective synthesis of 3-(α,α-dibromoacetyl)-4-hydroxy-6-methyl-2H-pyran-2-one has been achieved by bromination of DHA using CuBr2/CHCl3-EtOAc. The reaction of the above compound with different thioureas/thiomides/thiosemicarbazide offers a convenient and efficient method for the syntheses of 2-substituted 4-(4-hydroxy-6-methyl-2H-2-oxopyran-3-yl)thiazoles I (R = C6H5NH, 4-MeC6H4NH, 4-ClC6H4NH, etc.). These thiazoles were evaluated for their antimicrobial and antifungal activity.
Journal of Heterocyclic Chemistry published new progress about 3696-23-9. 3696-23-9 belongs to chlorides-buliding-blocks, auxiliary class Chloride,Thiourea,Amine,Benzene,Amide, name is 1-(4-Chlorophenyl)thiourea, and the molecular formula is C7H7ClN2S, Recommanded Product: 1-(4-Chlorophenyl)thiourea.
