## Abstract (12,13‐^13^C~2~)Retinal, (13,14‐^13^C~2~)retinal, (19‐^13^C)retinal and (20‐^13^C)retinal (1) were prepared in a simple fashion in high yield via a consecutive strategy. The key step is the reaction of a __N__‐methoxy‐__N__‐methylamide with an alkyllithium or a Grignard reagent. The pre
