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-caboline compounds. All structures of new compounds were confirmed by ¹H NMR, ¹³C NMR and HRMS.
