Novel hybrid vitamin, 3-O-retinoyl-L-ascorbic acid (3a) was conveniently prepared by reaction of sodium L-ascorbate with retinoyl fluoride. The 3-O-acylated structure was confirmed by the comparison of spectral data of its methylated compound with those of 3-O-methyl-2-O-retinoyl-L-ascorbic acid (20) prepared from 5,6-O-isopropylidene-3-O-methyl-L-ascorbic acid. 3-O-Retinoyl-L-ascorbic acid (3a) showed a reducing activity against the stable radical, α,α-diphenyl-β-picrylhydrazyl (DPPH).
