Synthesis of retinals labelled at positions 14 and 15 (with 13C and/or 2H)

Eight retinals labelled at positions 14 and 15 with 13C and/or 2H were obtained with 98 percent chemical purity, 92 percent 13C incorporation, 95 percent 2H incorporation at position 14 and 99 percent 2H incorporation at position 15. (14-13C)retinal, (15-13C)retinal and (14,15-13C)retinal were synthesized from (2-13C)-, (1-13C)- and (1,2-13C)acetonitrile, respectively, while for the synthesis of (14-2H)retinal, 2CH3CN was used.Via a three-step process these retinals were transformed into (14,15-2H)retinal, (14-13C,15-2H)retinal, (15-13C,15-2H)retinal and (14,15-13C2,15-2H)retinal.Their 13C-13C, 13C-2H and 13C-H NMR coupling constants were determined.
