Conformation of 1,4, 7,10-tetraoxacyclododeca-2,3-dion by nmr.

Abstract

Conformation of the 1, 4, 7, 10-tetraoxocyclododeca-2, 3-dion was analysed by NMR and found out that the “gouch” from of a-diester carbonyls arrange the methylene groups as the “go«ch, gouch, anti” (g+ , gi, a) unitsin equilibrium of pseudorotermers so that o^ygens are in non corner positions of “sguare” conformation.
