摘要
A general and efficient procedure for the synthesis of 2,3-disubstituted 5-azaindoles through the palladium-catalyzed heteroannulation of 4-acetamido-3-iodopyridines and diaryl-, dialkyl-, or arylalkylalkynes is described along with a study of the reaction regioselectivity. The preparation of 2-monosubstituted 5-azaindoles via sila-Sonogashira/5-endo cyclization is also reported. These methods allowed us to prepare 36 diversely substituted 5-azaindoles in good yields.
