Reaction Steps

All-trans-retinol was obtained as a gift from Dr. Christian Eckhoff of Hoffmann-LaRoche, Inc. (Nutley, N.J.), and 13-cis-retinol was purchased from Sigma. 9-cis-Retinol was synthesized by NaBH4 reduction of authentic 9-cis-retinaldehyde (Sigma) and subsequently purified by normal phase HPLC essentially as we have described for 11-cis-retinol synthesis and purification (25). All-trans-, 13-cis-, and 9-cis-retinaldehydes were purchased from Sigma.
