Abstract
Synthesis of chemically diverse heterocyclic scaffolds in DNA-encoded libraries is highly demanded. We herein reported a convenient one-pot multi-component on-DNA synthetic strategy to afford multi-substituted 2,3-dihydrofuran scaffolds via pyridinium ylide-mediated cyclization. This reaction exhibited modest to excellent conversions for a broad range of DNA-conjugated aldehydes, β-ketonitriles and pyridinium salts under mild reaction conditions. Furthermore, the compatibility of this strategy with DEL construction was verified by enzymatic DNA ligation, PCR amplification and mock library synthesis.
