Syntheses and UV/Vis properties of amino-functionalized fulgimides

Article abstract of DOI:10.1002/ejoc.200200680

Functionalized fulgimides are regarded as a promising class of photochromic compounds for modulating the structure and function of biomolecules. A new synthetic route to fulgimides bearing amino-functionalized substituents at the imide nitrogen atom has been developed. The synthesis of the fulgimides has been achieved by base-catalyzed cyclization of phenacyl esters of the succinamic acids derived from fulgides and N-Boc-protected alkyl- and aryl-substituted diamines with triethylamine or tert-butyllithium. The UV/Vis spectroscopic data and the photochromic properties of these new compounds have been studied. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
