合成路线1
该中间体在本合成路线中的序号:(I)Synthesis of the unsaturated acid precursor (V) is carried out as follows. Desilylation of 4-(trimethylsilyl)-3-butyn-2-ol (I) with tetrabutylammonium fluoride affords (II). The lithium acetylide generated from alkyne (II) is then carboxylated by CO2 to furnish the pentynoic acid derivative (III). Subsequent acetylation of the alcohol hydroxyl group of (III) leads to acetate ester (IV). Then, Lindlar hydrogenation of the triple bond gives rise to the cis alkene (V).
