Some new mono-and bis-polycyclic aromatic spiro-beta-lactams and bis-non spiro-polycyclic aromatic beta-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-beta-lactams were established by X-ray crystal analysis.
一些新的单环和双多环芳烃螺β-内酰胺和双非螺多环芳烃β-内酰胺已经通过[2+2]环加成反应从蒽-9-甲醛、2-萘甲醛和由 9H-呫吨-9-羧酸和苯氧乙酸衍生的烯酮衍生的亚胺合成得到。环加成产物通过光谱数据，包括 1H-NMR、13C-NMR、IR 和元素分析进行了表征。通过 X 射线晶体分析确定了其中一些单螺β-内酰胺的构型。
