An Expedient New Synthesis of Substituted Carbazoles via α-Oxoketene Acetals Through Heteroaromatic Anellation Methodology.
-Base-induced conjugate addition-elimination of indole-3-acetonitriles to α-oxoketene S,S-, O,S-and N,S-acetals followed by cyclization of the intermediate adducts with catalytic acid provides a new general, efficient and expedient method for the synthesis of substituted carbazoles. -(PATRA, P.
