该中间体在本合成路线中的序号：(XXV)

The hydrogenation of the double bond of (XVIII) with H2 and Lindlar catalyst affords the corresponding saturated aldehyde (XIX), which is condensed with the diazophosphonate (XX) giving the acetylenic derivative (XXI). The bromination of (XXI) with N-bromosuccinimide (NBS) and AgNO3 yields the bromoacetylenic compound (XXII), which is desilylated with HF and TBAF affording the dihydroxy derivative (XXIII). The resilylation of (XXIII) with CF3CO-N(Me)-Tms gives the bis(trimethylsilyl) derivative (XXIV), which is finally converted into the desired intermediate, the stannane (XXV) by reaction with tributyltin hydride, PPh3 and Pd dibenzylideneacetone complex.

合成路线2

该中间体在本合成路线中的序号：(XXV)

The condensation of intermediate (XXV) with intermediate (XXXVIII) by means of triphenylarsine and Pd dibenzylideneacetone complex in DMF gives the addition compound (XXXIX), which is desilylated with TBAF in THF yielding the immediate precursor (XL). Finally, the cyclic ketal group of (XL) is opened by means of H2SO4 in THF/water.
