Abstract
The dioxepine part of the title heterocycle adopts a chair conformatio n. The position of O1 opposite to the lone pair at the N atom and the inequality of the bond angles O1-S1-N1 much greater than O2-S1-N1 sugg est an n-sigma interaction of the lone-electron pair with the S(VI)[O ,O',N,C] tetrahedral moiety.
