An efficient and general approach for the synthesis of amphiphilic 1,2-amino alcohols is reported. The use of N-benzyl protecting groups is essential for obtaining good yields when opening a long-chain terminal epoxide with an amine.

Four aza and two thioanalogues of Annonaceous acetogenins were synthesized according to a general synthetic route. Two remote stereocentres in the analogues were set with high enantio‐ and diastereoselectivity in one step by hydrolytic kinetic resolution of a terminal bis‐epoxide.

A convergent total synthesis of the mono(tetrahydrofuran) annonaceous acetogenin murisolin, with a longest linear sequence of nine steps, is reported. Assembly of the complete carbon framework by crossmetathesis and late-stage tetrahydrofuran formation on the intact backbone are key elements of the synthesis.
