A general and concise synthesis of functionalized indoles via dominoreaction of N-aryl amides and ethyl diazoacetate has been developed. The methodology offers a great potential for the synthesis of biologically active and naturallyoccurring indole derivatives.
Reactions of 2-iodoanilines with ethyl buta-2,3-dienoate catalyzed by potassium carbonate and CuI in one pot generate the corresponding ethyl 2-methyl-1H-indole-3-carboxylate products in moderate yields under mild conditions. indoles - aniline - allenes - copper - catalysis
