4-Tosyl-1-oxa-4-aza-spiro-[4.5]deca-6,9-dien-8-one
Abstract:
In the mol-ecule of the title compound, C(15)H(15)NO(4)S, the two six-membered rings are almost parallel to each other [dihedral angle = 1.87 (9)°] and perpendicular to the mean plane through the five-membered ring [dihedral angles of 89.98 (10) and 89.04 (10)°]. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen-bonding inter-actions.
