Derivatives of tetrahydro-2,3,6,7,1H,5H,11H-(1)benzopyrano(6,7,8, i,j) quinolizinone-11 usable as markers for organic compounds, particularly biological compounds with a view to their detection by chemiluminescence or fluorescence

摘要

The invention relates to novel derivatives of tetrahydro-2,3,6, 7,1H,5H, 11H-(1)benzopyrano(6,7,8ij)quinolizinone in accordance with the formula: ##STR1## in which R.sup.1 represents 1) --NH--(CH.sub.2).sub.n -- R.sup.2 with n being an integer between 1 and 20 and R.sup.2 representing --N CS or NH--CO--CH.sub.2 X with X representing I, Br or Cl, orP P2) --NH--(CH.sub.2 --CH.sub.2 --O)m--CH.sub.2 --CH. sub.2 --R.sup. 3 with m being an integer between 1 and 30 and R.sup.3 representing a group chosen from among groups of formula ##STR2## in which p is an integer from 1 to 10 and X represents Br, Cl or I. These derivatives can be use as markers for organic compounds, in particular biological substances, for the detection thereof by chemiluminescence or fluorescence.
