Total synthesis of octosyl acid A. Intramolecular Williamson reaction via a cyclic stannylene derivative

The total synthesis of the title compound has been achieved. The key features involved (i) the construction of a carbon-linked furanoside-pyranoside by a cyclocondensation reaction of compound 8, (ii) the use of the pyran matrix to elaborate the required
