Synthesis of Dimeric Pyrrole-Imidazole Alkaloids
… synthetic challenges. A manganese(III)-mediated oxidative radical cyclization has been developed to construct the core skeleton of these pyrrole-imidazole dimers and its mechanism is investigated by the methods of computational chemistry. Ent-15-epi-5,11-dioxomassadine has been synthesized by …

Radical decarboxylation strategies for the synthesis of nitrogen-containing heterocycles
… this thesis describes the use of novel delayed radical precursors in Mn (OAc)3·2H2O mediated oxidative radical cyclization-fragmentation-dimerization processes from Banilides. The first part presents a sequential oxidative radical cyclization-decarboxylative-dimerization process from β-oxoacids, …

Biomimetic synthesis of meroterpenoid natural products using dearomatization strategies
… yield). The key biomimetic synthetic step was an oxidative radical cyclization cascade reaction, where four new carbon-carbon bonds, four new carbocyclic rings and five new stereocentres were formed in the one step. The first total synthesis of merochlorin A was achieved in five linear steps from …

Application of Mn(III) Oxidative Cyclizations to Natural Product Synthesis
… a brief review of manganese(III) acetate free radical oxidative cyclization chemistry and its application toward functionalizing nitrogen containing heterocycles. Exploration of a cyclopropane ring opening reaction using indoline, and subsequent manganese(III) cyclization chemistry will be …
