Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. HPLC of Formula: C8H4Cl2N2, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
Condensation of 4-amino-5-mercapto-3-p-(t-butylphenyl)-s-triazole 1 with cyanogen bromide gives 6-amino-3-p-(tbutylphenyl)-s-triazolo[3,4-b][1,3,4]thiadiazole 2 which on condensation of with chloranil yields 3,9-di-p-(t-butylphenyl)6,14-dioxo-bis-(s-triazolo[3,4-b] [1,3,4]thiadiazolo[3,2-b]-[imidazo[4,5-b]cyclohexane]-5a,6a-diene) 3. 3-p-(t-Butylphenyl)s-triazolo[3,4-b][1,3,4]thiadiazolo[3,2-b]-imidazo [4,5-b] quinoxaline 4 is obtained by a similar condensation of 2 with 2,3-dichloroquinoxaline. The reaction of 2 with alpha-haloketones followed by bromination affords 7-aryl-3-p-(t-butylphenyl)imidazo[2,1-b]-1,3,4-thiadiazolo[2,3-c]-s-triazoles 5 and their 6-bromo analogues 6 respectively. The antibacterial and anti-fungal activities of some of the compounds have also been evaluated.
