合成路线1
该中间体在本合成路线中的序号：(VII)The Horner-Emmons condensation of 4,4'-dibromobenzophenone (I) with triethyl phosphonoacetate leads to the 3,3-diarylpropenoate (II). Ester (II) is subsequently reduced to the allylic alcohol (III) employing DIBAL in cold THF. Suzuki coupling of aryl bromide (III) with phenylboronic acid (IV) furnishes 3,3-bis-(biphenyl-4-yl)-2-propen-1-ol (V). Coupling of allylic alcohol (V) with (S) ethyl 2-ethoxy-3-(4-hydroxyphenyl)propionate (VI) by means of 1,1'-(azodicarbonyl)dipiperidine (ADDP) and tributylphosphine under Mitsunobu conditions gives rise to the ether adduct (VII). Finally, saponification of the ethyl ester group of (VII) provides the target carboxylic acid.
