The first synthesis of (+)- and (−)-akolactone A is described by using Pd-catalyzed carbonylation. A comparison of the optical rotation of both enantiomers of akolactone A and the natural compound suggests that the absolute configuration at the 4-position of akolactone A is R.
本研究首次利用钯催化羰基化技术合成了(+)-和(-)-阿可内酯 A。通过比较阿可内酯 A 的两种对映体和天然化合物的旋光性,表明阿可内酯 A 的 4 位绝对构型为 R。
