De novo asymmetric synthesis of (−)-nanaomycin A
2018
Zhang, Qi | O'Doherty, George A.
The de novo asymmetric total synthesis of (−)-nanaomycin A is described. The entirely linear route required only 13 steps from commercially available starting materials (3% overall yield). Key transformations include a Claisen rearrangement, an asymmetric dihydroxylation, a regioselective tosylation, a diastereoselective intramolecular Friedel-Crafts alkylation and a nitrile hydrolysis. As the route relies on a Sharpless asymmetric dihydroxylation it is equally amenable for the synthesis of (+)-nanaomycin A.
