Quinoxalino[20,30:5,6][1,3,4]thiadiazino[2,3-b]quinazolin-15-one, a novel fused heterocyclic system, was

synthesized from a one-pot condensation reaction of 2,3-dichloroquinoxaline and 3-amino-2-thioxo-2,3-

Attempted heterocyclization of 5-bromo-2,4-diamino-6-substituted pyrimidines in a mixture of DMF and trialkylamines (Et3N or N,N-diisopropylethylamine) under mild conditions, led to the formation of new dehalogenated ...

Dehalogenation of 5-halogenopyrimidine derivatives in boiling pure water was accomplished in high yields. The substrate and pure water are the only two reaction components in this process. Dehalogenation takes place in the ...

Introduction:

A wide range of synthetically valuable transformations in organic chemistry involve reduction

process through which functionalization can be easily performed over the course of the reaction.
