Abstract

A hydroamination–double hydroarylation cascade using aniline derivatives bearing a trienyne moiety as the substrate was efficiently promoted by a gold (I) catalyst to produce benzo [a] naphtho [2, 1-c] carbazole derivatives in good yields. This reaction is applicable to various substituted trienyne-type anilines, including 2, 3-diethynylthiophene derivatives. The reaction of anilines bearing a tetraenyne and pentaenyne moiety allows direct ...
