This paper is dedicated to Prof. E. J. Corey for his elegant total syntheses of the fumagillin and ovalicin families. This work was partially supported by a Grant-in-Aid for Scientific Research on Priority Areas 16073219 from The Ministry of Education, Culture, Sports, Science, and Technology (MEXT).

Graphical Abstract

L-Proline-mediated α-aminoxylation is a key step in the enantio- and diastereoselective total syntheses of fumagillin, ovalicin, and related compounds (see scheme). These compounds contain a cyclohexane ring, two epoxides, and five or six contiguous stereogenic centers, and they display anti-angiogenesis or immunosuppressive properties.
