(+)-paeoniflorigenone, representative monoterpenes of Paeoniae Radix, have been accomplished starting with R-(−)-carvone via lipase catalyzed highly diastereoselective enzymatic acetylation. The latter synthesis also means the first total synthesis of (+)-paeonisuffral, a new monoterpene recently isolated from Moutan Cortex.
(R)(-)-香芹酮经脂肪酶催化的高度非对映选择性酶促乙酰化反应已成功完成了首个全部合成的(+)-pa烯内酯C和(+)-eon烯异黄酮(e药的代表性单萜)。后者的合成也意味着(+)-paeonisuffral的第一个全合成,这是最近从牡丹皮中分离出来的一种新的单萜。
