The total synthesis of both enantiomers of the title compound has been achieved in seven steps with 19% overall yield. The synthetic diamine differs in its NMR data and optical rotation from haliclorensin, a marinealkaloid for which the same structure had been proposed.

strategy previously reported by one of us and uses an efficient preparation of the quinoline-7,8-diol unit by modified Baeyer–Villiger and Skraupreactions. The O-benzyl protecting groups were removed in the last step of the synthesis by transfer hydrogenolysis without concomitant reduction of the quinoline ring. The method can be applied for the synthesis of halitulin analogues.
