Synthesis of CD3‐Labeled 11‐cis‐Retinals and Application to Solid‐State Deuterium NMR Spectroscopy of Rhodopsin.

Efficient synthesis of 11-Z-retinals labeled with 2H at the C5, C9, or C13 methyl groups is described. The 2H-labeled retinals were used to regenerate the visual pigment rhodopsin for structural in...
