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. category: quinoxaline, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
A novel series of pyrazoline and thiazole derivatives incorporating 2-pyrazolin-5-one moiety were synthesized starting from alpha,beta-unsaturated ketones under the effect of hydrazine derivatives and thiosemicarbazide. The obtained pyrazolines 4a, 4b were treated with different reagents to afford N-substituted pyrazolines 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b. N-Thiocarbamoyl pyrazolines 12a, 12b were cyclized using phenacyl bromide, 2,3-dichloroquinoxaline, and monochloroacetic acid afforded the novel pyrazolinyl thiazoles 13a, 13b, 14a, 14b, 15a, 15b, 16a, 16b, 16c, 16d, 16e, 16f. The newly synthesized compounds were characterized by analytical and spectral data.
