Ethyl 5-(5-oxo-2,3-dihydro-5H-oxazolo[2,3-a]isoindol-9b-ylmethyl)-4-(2,5,5-trimethyl-1,3-dioxan-2-yl)isoxazole-3-carboxylate: the product of a novel synthetic method
The title compound, C24H28N2O7, is the product of a novel synthetic procedure in which a highly functionalized heterocycle is formed. The crystal packing involves dimers, utilizing non-classical weak C—H…O interactions (ca 3.36–3.46 Å) and an antiparallel – interaction between two of the pseudo-aromatic isoxazole moieties. These dimers are associated into a three-dimensional network via further non-classical hydrogen bonding.
