Layered Compounds. LXIV. Syntheses and Charge Transfer Spectra of Multilayered Paracyclophanequinones

Three isomeric triple-layered and two isomeric quadruple-layered charge transfer cyclophanes containing benzoquinone and dimethoxybenzene moieties have been synthesized together with two triple-layered and two quadruple-layered paracyclophanequinones.The structures of the isomers were determined by 1H- and 13C-NMR spectra and/or alternative syntheses.By comparing the CT bands of a series of dimethoxycyclophanequinones with those of the corresponding cyclophanequinones, it is concluded that the CT stabilization of multilayered dimethoxyquinones should be attributedmainly to the ?-basicity of the durene ring which faces the acceptor quinone ring and partly to the decreasing ?-basicity of dimethoxybenzene ring as the layer number increases.No orientational dependence of quinone and dimethoxybenzene moieties on CT transition was observed in the multilayered series.

SYNTHESIS OF OXIRANYLQUIONOES AS NEW POTENTIAL BIOREDUCTIVE ALKYLATING AGENTS

1,4-Benzoquinones and 1,4-naphtoquinones carrying oxiranyl substituents have been synthesized as potential bioreductive alkylating agents.The method presented here involves the syntheses of 1,4-dimethoxybenzaldehydes or 1,4-dimethoxynaphtaldehydes, and co
