(-)-rhazinilam was synthesized in three major steps, namely the pyrrole synthesis, selective C[bond]H bondactivation, and direct macrolactam formation. The key step involved asymmetric C[bond]H bond functionalization (dehydrogenation) of the diethyl group segment in intermediate 6. This was achieved by the attachment of chiral platinum complexes to the proximal nitrogen atom. A high degree of selectivity
