Crystal Structure of Ethyl (2Z)-2-(4-acetyloxybenzylidene)-7-methyl-3-oxo-5-phenyl-2,3-dihydro-5H-[1,3]thiazolo[3,2-a]pyrimidine-6-carboxylate

Abstract

In the molecular structure, the central pyrimidine ring is significantly puckered, assuming an intermediate conformation between a screw boat and boat form. In the solid state, the short intramolecular C-H…S, intermolecular C-H…O and π-π stacking interactions contribute to the crystal packing.
