Abstract: Some new mono-and bis-polycyclic aromatic spiro-β-lactams and bis-non spiro-polycyclic aromatic β-lactams have been synthesized from imines derived from anthracene-9-carbaldehyde, 2-naphtaldehyde and a ketene derived from 9H-xanthene-9-carboxylic acid and phenoxyacetic acid by a [2+2] cycloaddition reaction. The cycloadducts were characterized by spectral data, including 1H-NMR, 13C-NMR, IR and elemental analyses. The configurations of some of these mono-spiro-β-lactams were established by X-ray crystal analysis.
Keywords: mono- and bis-spiro-β-lactam; polycyclic aromatic imine; 9H-xanthene-9-carboxylic acid; phenoxyacetic acid; [2+2] cycloaddition; tosyl chloride
