A Heck cyclisation approach is described for the rapid synthesis of a library of natural product-like small molecules, based on the phenanthridine core. The synthesis of a range of substituted benzylamine building blocks and their incorporation into the library is reported, together with a highly selective cis-dihydroxylation protocol that enables access to the target compounds in an efficient manner. Biological evaluation of the library using zebrafish phenotyping has led to the discovery of compound 20c, a novel inhibitor of early-stage zebrafish embryo development.
