合成路线1
该中间体在本合成路线中的序号：(XX)The preparation of the epoxide precursor (XV) can also be carried out by an alternative route starting from the chiral hydroxypropiophenone (XVIII), obtained from ethyl (S)-lactate. Hydroxy ketone (XVIII) was converted to triflate (XIX), which was condensed with the sodium salt of imidazolone (XII), yielding adduct (XX). Addition of (dimethylisopropoxysilyl)methylmagnesium chloride to the propiophenone (XX) furnished carbinol (XIX). Oxidative desilylation of (XIX) with H2O2 in the presence of NaHCO3 afforded diol (XXII). This was converted to the corresponding mesylate (XXIII) and then cyclized to oxirane (XV) in the presence of K2CO3.
