6-Methoxy-1,2,3,9-tetrahydro-4H-carbazol-4-one oxime (3b) was synthesized by one-pot reaction. The combination of Fischer indole synthesis and oximation led to simplified process and increased productivity. This reaction could proceed in one pot in weak alkaline solution at mild temperature since oximation has facilitated the Fischer indole cyclization. Differences in tautomerization between carbonyl and oximyl were considered as the key factor that influenced the cyclization.

Key words: one-pot synthesis, Fischer indole synthesis, oximation, tautomerism
