Unfortunately in the online published article, the name of compound “l-salicylidenealanine” was published with incorrect spelling in the section “Synthesis of l‑salicylideneaniline (1a)”. The section should correctly read as “Synthesis of l-salicylidenealanine”.

The original article has been corrected.
