## Abstract __7E,13E__‐11,19‐10,20‐dimethanoretinal (1) and its 13__Z__ isomer 2 were prepared from β‐ionone, using the novel synthon 2‐(diethoxyphosphinyl)‐5,5‐dimethoxyhexanenitrile. This synthon was also used to prepare __7E,9E,13E__‐10,20‐methanoretinal (3) and its 13__Z__ isomer 4 in high yiel
