General description

2,3-Dichloroquinoxaline reacts with 6-aminothiouracil in ethanol/TEA to form 6-amino-2-(3-chloroquinoxalin-2-ylthio)pyrimidin-4(3H)-one. It reacts with cholest-5-en-3-one semicarbazone/thiosemicarbazone to form steriodal cholest-5-en-3-oxazolo and thiazoloquinoxaline.

Application

2,3-Dichloroquinoxaline was used in the synthesis of mono and 2,3-disubstituted quinoxalines. It was used in solid phase synthesis of HPLC chiral stationary phase containing the N,N′-dialkyl-2,3-diaminoquinoxaline group as a linking structure.
