A UNIFIED STEREOCHEMICAL MODEL FOR THE POLYEPOXIDE CYCLIZATION ROUTE TO MARINE POLYETHER TOXINS
Alvarez, Eleuterio,Rodriguez, Matias L.,Zurita, Dacil,Martin, Julio D.
, p. 2253 - 2254 (1991)
A stepwise intermediacy of oxocarbenium ions of type 2 provide strong support for the feasibility of the polyepoxide approach to ortho- and spiro-condensed polyether toxins of marine origin.
