## Abstract New procedures are described for the synthesis of α,β‐ethylenic and acetylenic aldehydes from 2‐butene‐ and 2‐butyne‐1,4‐diol, respectively (see __Scheme 1__). These are applied to the preparation of a particular δ‐acetylamino‐α,β‐ethylenic aldehyde ((__E__)‐**5**) as well as of its ace

A catalytic amount of N-nitroso-2-aryl-1,3-oxazolidines leading to the aromatization of Hantzsch 1,4-dihydropyridines (DHPs) was successfully achieved. A catalytic mechanism for the reaction is proposed.
