Disclosed is a method of preparing an optically pure (R)- or (S)-tetrahydrofuranyl ketone. By such a method, (R)- or (S)-2-tetrahydrofuran amide is converted to (R)- or (S)-2-tetrahydrofuran nitrile through dehydration in the presence of a dehydrating agent and an amine base. Then, thus prepared (R)- or (S)-2-tetrahydrofuran nitrile is nucelophilic addition-reacted with a nucleophile, followed by hydrolyzing, thereby produce (R)- or (S)-tetrahydrofuranyl ketone having high optical purity, while minimizing production of other by-products.
本发明公开了一种制备光学纯(R)-或(S)-四氢呋喃基酮的方法。通过这种方法,(R)-或(S)-2-四氢呋喃酰胺在脱水剂和胺基存在下转化为(R)-或(S)-2-四氢呋喃腈。然后,所制备的(R)-或(S)-2-四氢呋喃腈与亲核试剂进行亲核加成反应,随后水解,从而产生具有高光学纯度的(R)-或(S)-四氢呋喃基酮,同时最小化其他副产物的产生。
