合成路线1
该中间体在本合成路线中的序号：(XIX)Then group of (XV) was oxidized with 4-benzylpyridinium dichromate to the aldehyde (XVI). 3-(Tributylstannylmethyl)pyridine (XVIII), prepared from lithiated 3-picoline (XVII) and Bu3SnCl in the presence of HMPA, was coupled to bromotetrahydronaphthalene (XVI) under palladium catalysis to provide the pyridylmethyl derivative (XIX). Wittig reaction of (XIX) with phosphorane (IX) gave acrylate (XX), which was reduced with SmI2 or with NaBH4 and CoCl2 to the tetrahydronaphthylpropionic ester (XXI). Finally, the ester group of (XXI) was hydrolyzed with NaOH in MeOH-H2O to give the title acid.
