合成路线1
该中间体在本合成路线中的序号：(XXXII)Allyl alcohol (XXX) was converted to chloride (XXXI) by means of N-chlorosuccinimide and dimethylsulfide. Displacement of the chloride ion of (XXXI) with lithium diphenylphosphide, followed by H2O2 oxidation of the resulting phosphine gave the phosphine oxide (XXXII). This was subjected to a Wittig condensation with the functionalized indanone (XXXIII) to produce the triene adduct (XXXIV). Final desilylation of (XXXIV) to the title compound was effected by treatment with tetrabutylammonium fluoride in THF
