Studies towards the synthesis of the zaragozic acids: Synthesis of the bicyclic acetal core of zaragozic acid C.
Paterson, Ian,Fessner, Klaus,Finlay, M. Raymond V.
, p. 4301 - 4304 (2007/10/03)
The bicyclic core 6 of zaragozic acid C (7) was prepared by the epoxide cyclisation reaction 21 → 22 → 15. Acetal 15 was also obtained by acid-promoted rearrangement of the isomeric acetal 19.
The asymmetric syntheses of the C-1 sidechains of zaragozic acid A and zaragozic acid C
Robichaud, Albert J.,Berger, Gregory D.,Evans, David A.
, p. 8403 - 8406 (2007/10/02)
The asymmetric syntheses of the C-1 sidechains of zaragozic acid A and C are described. Aldol reaction defines the chirality at C-4' and C-5' in two independent routes. Multigram preparation as well as a route amenable to derivatization are highlights of
