## 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
1 and alkenes 2 with an electron-withdrawing or an electron-donating group 2 a-f and 2 g-h regioselectively yields the 4-substituted and the 3-substituted 2-hydroxy-1,2,3,4\_tetrahydropyridines 3 respectively. Dehydratisation of 3 with electron-withdrawing groups at C-4 gives the 1,4\_dihydropyridin
