The reaction sequence involved a Sharpless asymmetric epoxidation as the key-step to induce chirality. Enantiomeric conversion gave rise to the opposite unnatural serie. The structural dimensions of (-)3'6'-epoxyaurapten have been ascertained by means of X-ray cristallography. This route allows the preparation of related molecules.
                                    3'6'Epoxyaurapten和marmin是通过立体控制的方式从非手性前体中以外消旋形式,然后以光学活性形式合成的。合成策略是仿生型。反应顺序涉及Sharpless不对称环氧化反应,是诱导手性的关键步骤。对映异构体转化产生了相反的不自然序列。(-)3'6'-环氧锐
钛型的结构尺寸已经通过X射线晶体描记法确定。该途径允许制备相关分子。
