Summary:
In order to keep up with the high demand for biologically active molecules, chemists devised several synthetic strategies to access novel chemical spaces. The two main strategies to construct new scaffolds are to revisit underexploited or forgotten reactions or to devise new transformations. We are exploring a unique and underexploited reaction, the Himbert–Henn cycloaddition, to produce complex molecular scaffolds in a single step (strategy 1). In a second novel approach, we are modifying the Hantzsch 4-component reaction (4CR) by incorporating an α-amino ester residue to construct new molecules (strategy 2). Both of these reactions have great potential to synthesize novel and chiral molecules from proteinogenic α-amino esters. These unprecedented and complex polycyclic molecules have potential application in medicinal chemistry and natural product synthesis. 4-aza-podophyllotoxins obtained by the Hantzsch-4CR have been proven to be potent as anti-leukemia, anti-colon cancer, and vascular disrupting agents (with nanomolar activity).
