Synthesis by deamination reaction and crystal structure at 120 K of (16Z,19E)-18-oxo-N-(pyridin-2-yl)-6,7,9,10-tetrahydro-18H-dibenzo[h,o][1,4,7]trioxacyclohexadecine-17-carboxamide
Abstract:The title compound, C27H24N2O5, is a product of the deamination reaction from aza-14-crown-4 ether containing the γ-piperidone subunit. The title molecule contains a 16-membered macrocycle with the conformation of the C—O—C—C—O—C—C—O—C polyether chain being t–g
(-)–t–t–g
(+)–t (t = trans, 180°; g = gauche, ±60°). The dihedral angle between the planes of the benzene rings fused to the aza-14-crown-4-ether moiety is 31.11 (14)°. The cavity size inside the macrocycle is 4.72 Å.… Show more
