実験手順
Pentafluoropropanal methyl hemiacetal (14.9 g, 82.8 mmol) and L-leucinol (9.7 g, 82.8 mmol) were dissolved in 100 mL of benzene and heated to reflux overnight in a flask equipped with a Dean-Stark tube. The resulting solution was cooled and concentrated to provide the title compound as an oil which was used directly in the following step.
