A copper-catalyzed azide-ynamide cyclization to synthesize isoquinoline derivatives is reported. First, α-imino copper carbene intermediate is generated via Cu(I)-catalyzed azide-ynamide cyclization, then this copper carbene can be captured by indoles and anilines to form C—H and N—H insertion products. The notable advantages of this method include a simple procedure, mild reaction conditions and widespread availability of the substrates. Thus, this protocol provides a highly convenient and efficient route for the preparation of natural products and active molecules which contain the isoquinoline-indole or isoquinoline-aniline skeletons.

Key words: cyclization reaction, copper catalysis, copper carbenes, ynamides
