NOVEL 2,3,6,7,1H, 5H, 11H- (1) BENZOPYRANO (6,7,8IJ) QUINOLIZINONE-11 TETRAHYDRO DERIVATIVES USEFUL AS MARKERS OF ORGANIC COMPOUNDS, IN PARTICULAR BIOLOGICAL COMPOUNDS, FOR THE DETECTION OF THESE COMPOUNDS BY CHEMILUMINESCENCE OR FLUORESCENCE.

摘要

The invention relates to novel 2,3,6,7,1H, 5H, 11H- (1) benzopyrano (6,7,8ij) quinolizinone tetrahydro derivatives having the formula: ## STR2 ## DRAWING IN BOPI) BR/ BR/ wherein R1 represents BR/ (CF DRAWING IN BOPI) BR/ BR/ where n is an integer from 1 to 20 and X is I, Br or Cl, or BR/ (CF DRAWING IN BOPI) BR/ BR/ with m being an integer ranging from 1 to 30 and R2 representing a hydrogen atom or the radical of formula In which p is an integer ranging from 1 to 10. These derivatives can be used as markers of organic compounds, in particular biological substances, for detect them by chemiluminescence or fluorescence. / P
