Facile synthetic approach for 5-aryl-9-hydroxypyrano [3,2-f] indole-2(8H)-one
An appropriate method for the synthesis of 5-aryl-9-hydroxypyrano[3,2-f]indole-2(8H)-one was described. The targeted compounds were obtained starting from vanillin via nine steps. Interestingly, in the final cyclization step, the intermediate 4-(2-halogeno phenyl)-7-methoxy-1H-indole-6-yl propiolate...
