合成路线:Reaction of 4-ethynylanisole (I) with nido-decaborane (II) in acetonitrile/benzene affords compound (III),which is then converted into (V) by reaction with BuLi in DME followed by treatment with CuCl and condensation with 2-(11-bromo-n-undecyloxy)tetrahydro-2H-pyran (IV) in pyridine.Removal of the THP group with p-toluenesulfonic acid in MeOH gives alcohol (VI),which is oxidized with CrO3 and H2SO4 in acetone to provide carboxylic acid (VIII) and ester (VII).Ester (VII) is then converted into carboxylic acid (VIII) by hydrolysis with H2SO4 in dioxane/H2O,which is demethylated with BBr3 in CH2Cl2.Finally,the resulting compound is coupled with butylamine (IX) by means of DCC in acetonitrile.
