Description and Uses
2,3-Dichloroquinoxaline (DCQX) can be used as a substrate for nucleophilic aromatic substitution (SNAr) reactions and is a versatile building block for the synthesis of many quinoxaline derivatives. 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.
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.
