## Abstract Syntheses of the three isomeric bromo‐1,5‐naphthyridines from 2‐hydroxy‐1,5‐naphthyridine, 3‐amino‐5‐bromopyridine (__Skraup__‐synthesis) and 4‐hydroxy‐1,5‐naphthyridine are described. New methods for the preparation of 2‐ and 3‐amino‐1,5‐naphthyridine are given. Some physical and che
## Abstract The four isomeric 5, 10‐pentadecadienals **1**, **2**, **3** and **4** were prepared by stereo‐selective routes from acetylenic precursors. Two of them, **2** and **4**, were also made by __Wittig__ reaction from 2‐hydroxytetrahydropyran **(29)**. 2‐Hydroxytetrahydropyran **(29)** yield
