Convergent synthesis of the A-J ring system of yessotoxin

Torikai, Kohei,Watanabe, Koji,Minato, Hiroaki,Imaizumi, Tomoyoshi,Murata, Michio,Oishi, Tohru

, p. 2368 - 2372 (2008)

A highly convergent synthesis of the A-J ring system of yessotoxin was achieved. A convergent strategy via α-cyano ethers was extensively applied in the assembly of the F and IJ ring fragments to afford the FGHIJ ring unit, followed by coupling with the ABC ring unit.
