The absolute configuration of (−)-licochalcone E (1) was determined to be (S) via the first enantioselective total synthesis of the compound. The chirality in (S)-(−)-licochalcone E (1) was installed by asymmetric methylation of the Evans' oxazolidinone derivatives.
通过该化合物的第一次对映选择性全合成,确定(-)-利加氢可的环烯E(1)的绝对构型为(S)。通过(E )的恶唑烷酮衍生物的不对称甲基化来安装(S)-(-)-利古耳酮E(1)中的手性。
