A series of new chiral 2(5H)-furanone derivatives containing bis-1,2,3-triazole moiety were designed and synthesized from (5S)-5-alkoxy-3,4-dihalo-2(5H)-furanones 1, dicarboxyl amino acids 2, propargyl bromide, and organic azides 5 under mild conditions via the sequential three steps, including asymmetric Michael addition-elimination, substitution and no-ligand click reaction. Twelve new intermediates, including N-[5-alkoxy-2(5H)-furanonyl] dicarboxyl amino acids 3 and their corresponding propargyl esters 4, and twelve target molecules 6 were characterized by FTIR, 1 H NMR, 13 C NMR, MS and elemental analysis. The influences of different synthetic conditions and substrates in each step were investigated. The research provides a new method and idea for the synthesis of 2(5H)-furanone compounds with polyheterocyclic structure due to the diversities of four basic unit molecules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
