Abstract
Bischler-Napieralski reaction of N-(2-indol-4-ylethyl) acetamide (II) gave pyridoindole (III) and azepinoindole (IV), N-(2-indol-5-ylethyl) acetamide (V) afforded pyridoindoles (VI and VII), N-(2-indol-6-ylethyl) acetamide (XIII) gave pyridoindoles (XIII and XIV) and N-(2-indol-7-ylethyl) acetamide (XIX) yielded pyridoindole (XX). These reactivity of indole was supported by calculated charge density with CNDO/2.
