The totalsynthesis of three diastereomeric matrine natural products is reported. The 8-step synthesis commences with simple acyclic precursors, forms all 4 rings of the tetracyclic natural product framework, and forges 10 of the 20 covalent bonds of the target structure. A cross-conjugated triene is positioned at the core of an acyclic branched structure. This precursor collapses to the tetracyclic
