合成路线1
该中间体在本合成路线中的序号：(III)2-Iodo-6-(4-chlorophenylsulfonyl)amino-5,6,7,8-tetrahydro-naphthyl-1-carbaldehyde (I) was coupled with 3-(tributylstannyl-methyl)pyridine (II) in the presence of Pd(PPh3)4 in N-methylpyrrolidine (NMP) at 110 C to afford the pyridinylmethyl derivative (III). Subsequent coupling of (VI) with (4-carboxybutyl)triphenylphosphonium chloride (IV) in the presence of potassium tert-butoxide in THF at low temperature provided a mixture of E and Z hexenoic acids (V), from which the target (E) isomer was isolated by column chromatography.
