The synthesis of novel 3,4-dihydro-1,2,5,7,4-tetroxazocine derivatives via extended [3 + 3 + 2] cycloaddition reactions between a carbonyl oxide, a nitrone and an aldehyde

Abstract

Ozonolysis of acenaphthylene in the presence of a nitrone 2 yields the corresponding polycyclic peroxide 5 containing the novel dihydro-1,2,5,7,4-tetroxazocine ring system; the structure of the crystalline adduct 5a has been unambiguously determined by X-ray crystallographic analysis.
