Outline of Final Research Achievements |
An enantioselective total synthesis of (+)-Mangromicin A has been accomplished. Naturally occurring mangromicins are novel anti-trypanosomal compounds, which have been discovered by our group. The tetrahydrofuran ring of mangromicin A, possessing a tetra-substituted carbon center, was constructed by Mukaiyama-type vinylogous alkylation via a cyclic oxocarbenium intermediate derived from γ-hydroxy ketone, with ideal stereoselectivity, and the 4-hydoxy-dihydropyrone scaffold was generated via Dieckmann cyclization at a late stage of the total synthesis. The reliable asymmetric synthesis of (+)-mangromicin A has revealed the absolute configuration of the naturally occurring mangromicin A.
