Abstract Hyrtiosulawesine was isolated from Indonesian specimens of the marine sponges Hyrtios erectus and H. reticulatu in 2002. We report here the first total synthesis of hyrtiosulawesine using an efficient and convenient synthetic strategy which could be widely used in the synthesis of other β-carboline compounds. All structures of new compounds were confirmed by 1H NMR, 13C NMR and HRMS.
