A multicomponent coupling reaction (MCR) is a highly efficient process that is capable of producing diversely functionalized molecules. These reactions can efficiently form several new bonds and generate stereocenters in a one-pot process. While there are many variations of MCRs, isocyanide-based MCRs (IMCRs) are widely utilized in the pharmaceutical industry due to their apparent capability to produce peptide-like products. One specific example of an IMCR is the Ugi-Smiles reaction which combines an aldehyde, an amine, a phenol, and an isocyanide to yield α-aminoacyl amide derivatives. IMCRs can also be used in combination with another reaction to produce more drug-like scaffolds. For example, a Diels-Alder cyclization can occur immediately following an MCR to create a more complex, cyclic product.
This work describes a novel dual Ugi-Smiles Diels-Alder process. The Ugi-Smiles reaction occurs along with an intramolecular Diels-Alder with furan (IMDAF) cyclization to prepare epoxyisoindolines, heterocyclic compounds that are precursors to biologically active molecules. Through evaluation of variations in reaction components, a small library of compounds were prepared, providing insight into the scope of these reactions and the stereochemistry of the products.
