Uses

4''''-(Pentyloxy)-[1,1'':4'',1''''-terphenyl]-4-carboxylic Acid is an intermediate used in the synthesis of Anidulafungin (A673000) which is a semisynthetic echinocandin that inhibits glucan synthase, an enzyme important in the formation of (1→3)-β-D-glucan, a major fungal cell wall component, and thus is used as antifungal drug.

Synthesis

289706-68-9

5731-12-4

158938-08-0

General procedure for the synthesis of 4''-n-pentyloxy[1,1':4',1'']terphenyl-4-carboxylic acid from the compound (CAS: 289706-68-9) and 4'-iodo-[1,1'-biphenyl]-4-carboxylic acid: 20.1 g of 4'-iodo[1,1']biphenyl-4-carboxylic acid, 13.1 g of sodium carbonate and 21.4 g of 4-n-pentyloxyphenylboronic acid glycol ester were added to 260 g of dimethyl sulfoxide (DMSO). Subsequently, 160 mg of PdCl2(PPh3)2 was added as a catalyst and the reaction mixture was heated to 100-110 °C and maintained for 2 hours. Upon completion of the reaction, the mixture was cooled to 40 °C and filtered, and the solid was washed with DMSO. The resulting solid was suspended in 100 mL of water, heated to 80 °C and 47 g of 37% sulfuric acid was slowly added dropwise over a period of 1 hour. After the dropwise addition, the reaction solution was continued to be stirred at 80 °C for 30 min, followed by cooling to 40 °C and filtration. Finally, the solid was dried and crystallized from dimethylacetamide to afford 18 g (81% yield) of 4''-n-pentyloxy[1,1':4',1'']terphenyl-4-carboxylic acid of >99% purity.
