TLDR A rigid compound with a common structural motif was successfully synthesized.
The article outlines a three-step synthesis method for aryl-substituted bicyclic diketones, focusing on the transformation of cyclopent-2-en-1-one into a single meso isomer of compound 4. This process involves reactions with phenylmagnesium bromide and condensation, with selectivity attributed to steric and electronic factors. The structure of the synthesized compound, 3a-Phenylhexahydropentalene-1,6-dione, was confirmed using spectroscopic techniques and single-crystal X-ray diffraction, achieving a 68% yield. The study highlights the compound's potential in medicinal and synthetic chemistry and was supported by the Department of Science and Technology of Henan Province and the Pingyuan Laboratory.
