A simple synthesis of dialkyl 2-(alkylamino)-5-[alkyl({2-[4-({alkyl[5-(alkylamino)-3,4-bis(alkoxycarbonyl)-2-furyl]amino}carbonyl)-2-quinolyl]-4-quinolyl}carbonyl)amino]-3,4-furandicarboxylate
derivatives is described. This involves reaction of isocyanides,
dialkyl acetylenedicarboxylates, and bicinchoninic acid (BCA) in
MeCN-THF at 25 ˚C for 36 hours.
dialkyl acetylenedicarboxylate - isocyanide - bicinchoninic
acid - multicomponent reaction - bicinchoninic amide
