Y. Ushigoe et al., NEW METHODS FOR THE SYNTHESIS OF OXY-FUNCTIONALIZED 1,2,4-TRIOXANES AND 1,2,4-TRIOXEPANES FROM UNSATURATED HYDROPEROXY ACETALS, Tetrahedron letters, 38(50), 1997, pp. 8753-8756
Oxy-functionalized 1,2,4-trioxanes or 1,2,4-trioxepanes were produced
by either autoxidation of the unsaturated hydroperoxy acetals 1, or th
e acid-catalyzed cyclization of epoxy hydroperoxides 9 which were read
ily prepared from 1. By the appropriate choice of cyclization procedur
e, the structures of the resulting cyclic peroxides could be efficient
ly controlled. (C) 1997 Elsevier Science Ltd.
