Glutaric anhydride → 5-(((2E,4E,6E,8E)-3,7-dimethyl-9-(2,6,6-trimethylcyclohex-1-en-1-yl)nona-2,4,6,8-tetraen-1-yl)oxy)-5-oxopentanoic acid

Reaction Steps

Glutaric anhydride (220 mg, 1.93 mmol) and retinol (500 mg, 1.75 mmol) were dissolved in dichloromethane (5 mL) in an amber-colored vial. Triethylamine (513 ul, 3.68 mmol) was added and the vial was flushed with argon. Reaction mixture was allowed to stir at room temperature for 4 hours. The material was concentrated and purified by silica gel chromatography with a dichloromethane/methanol gradient. Fractions were pooled and concentrated to yield yellowish oil (700 mg). The product was verified by NMR.
