A highly effective procedure is reported to synthesize 1,2-aminoalcohols by regio- and chemo-selective ammonolysis of mono-substituted epoxides. Additive- and concentration-effects were studied, revealing that (1) methanesulfonic acid is most effective among the additives tested and (2) formation of bis-adducts is practically eliminated at [C] ≤ 40 mM. The optimum condition thus identified was successfully applied to the final step of the synthesis of potent anti-tumor compound E7389.
