Abstract
Isocyanide multicomponent reactions (IMCRs) provide access to a plethora of molecular architectures. Four IMCRs have been translated to a DNA-barcoding strategy involving the use of chemically stabilized DNA barcodes coupled to a controlled-pore glass solid support. These are the Ugi reaction, the Gröbke–Blackburn–Bienaymé reaction, the Ugi-azide reaction, and the Ugi–aza-Wittig reaction. The reactions were all performed using DNA-tagged aldehydes, and provide diverse scaffolds. The DNA used in this barcoding strategy was composed of three nucleobases: thymine, cytosine, and 7-deaza-adenine, as a more depurination-resistant congener of adenine.
