Synthesis and crystal structure of tert-butyl 1-(2-iodobenzoyl)cyclopent-3-ene-1-carboxylate

Abstract

1-(2-Iodobenzoyl)-cyclopent-3-ene-1-carboxylates are novel substrates to construct bicyclo[3.2.1]octanes with antibacterial and antithrombotic activities. In this context, tert-butyl 1-(2-iodobenzoyl)-cyclopent-3-ene-1-carboxylate, C17H19IO3, was synthesized and structurally characterized. The 2-iodobenzoyl group is attached to the tertiary C atom of the cyclopent-3-ene ring. The dihedral angle between the benzene ring and the mean plane of the envelope-type cyclopent-3-ene ring is 26.014;(3)°. In the crystal, pairs of C-H..O hydrogen bonds link the molecules to form inversion dimers.
