Abstract

Abstract A number of new methyl derivatives of linear and angular pyrrolocoumarins were synthesized by direct Fischer's indole synthesis. In the same way some linear 2H, 10H- pyrano [2, 3-b] carbazol-2-one and angular 2H, 7H-pyrano [3, 2-c] carbazol-2-one were prepared. The synthesis was performed starting from the 4-methyl-7-aminocoumarin and methyl groups were introduced into positions which look most promising for the ...
