4′-(N-(Propargyl)pyrrol-2-yl)-2,2′:6′,2′′-terpyridine
A new terpyridine molecule, bearing a N-propargylated pyrrole, was prepared and characterized. Its synthesis was based on a Krohnke-type reaction between 2-acetylpyridine and N-propargylpyrrole-2-carboxaldehyde in a basic medium. An allene-containing terpyridine was also obtained as a by-product.
1-{4-[(Hexyloxy)methyl]pyridin-2-yl}ethanone
A new member of the 2-acetylpyridine family has been prepared and characterized by NMR and IR spectroscopies.
1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne
A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of ...
4′-(N-(Propan-1,2-dienyl)pyrrol-2-yl)-2,2′:6′,2″-terpyridine
A new pyrrole-substituted terpyridine derivative that possesses an allene moiety was obtained as an “unexpected” sole product during an attempt to alkylate the N-atom of pyrrole with propargyl bromide in order to obtain an alkyne-functionalized terpyridine.
