Hexamethylenetetramine-based ionic liquid/MIL-101(Cr) metal–organic framework composite: a novel and versatile tool for the preparation of pyrido[2,3-d:5,6-d′]dipyrimidines
Keyword(s):
In this study, HMTA-BAIL@MIL-101(Cr) was prepared as a novel catalyst for the synthesis of dipyrimidine derivtives by the reaction of barbituric acids, 6-aminouracil/6-amino-1,3-dimethyl uracil, and arylaldehydes under solvent-free conditions.
