Total synthesis of borrelidin

(Chemical Equation Presented) The total synthesis of borrelidin has been achieved. The best feature of our synthetic route is macrocyclization at C11-C12 for the construction of an 18-membered ring after esterification between two segments. A detailed examination of the macrocyclization led us to the samarium(II) iodide-mediated intramolecular Reformatsky-type reaction as the most efficient synthetic approach. The two key segments were synthesized through regioselective methylation, directed hydrogenation, stereoselective Reformatsky-type reaction, and MgBr2·Et2O-mediated chelation-controlled allylation.

Total synthesis of (-)-borrelidin

Matrix presented. The total synthesis of borrelidin has been achieved. The best feature of our synthetic route is Sml2-mediated intramolecular Reformatsky-type reaction for macrocyclization after esterification between two segments. The two key segments were synthesized through chelation-controlled carbotitanation, chelation-controlled hydrogenation, stereoselective Reformatsky reaction, and MgBr2·Et2O-mediated chelation-controlled allylation.
