合成路线3

该中间体在本合成路线中的序号：(LIV)

The elimination of the Pmb protecting group of (L) by means of DDQ in dichloromethane affords compound (LI), which is brominated with NBS and AgNO3 in acetone to provide the bromoacetylene derivative (LII). The reaction of (LII) with tributyltin hydride, Pd2(dba)3 and PPh3 leads to the vinylstannane (LIII), which is condensed with the chiral tetracyclic macrolactone intermediate (XXXVI) by means of PdCl2(CH3CN)2 in DMF to give the cyclic precursor (LIV). Finally, this compound is submitted to an acidic hydrolysis by means of TsOH and BO3H3 in THF to provide the target Sanglifehrin A
