U. Holzgrabe et al., CERIUM(IV) OXIDATIONS .10. OXIDATION OF O MEGA-PHENYLALKYLDICARBONYL-ANALOGOUS AND DICARBONYL-ANALOGOUS DERIVATIVES, Archiv der pharmazie, 327(8), 1994, pp. 515-523
Oxidations of the omega-phenylalkylmalonate derivatives 1a-f afford cy
clization products 2 as well as nitro-, alcohol and acetoxy compounds
3-7. The distribution of products depends sensitively on the temp, and
on the water content of the reaction medium and as well on the chemic
al nature of the carbonyl functions. Ce3+-ion formed during the reacti
on is responsible for the observed ring-opened side products.
