Aromatizing olefin metathesis by ligand isolation inside a metal- organic framework

The aromatizing ring-closing metathesis has been shown to take place inside an extended porous framework. Employing a combination of solvent-assisted linker exchange and postsynthesis modification using olefin metathesis, the noninterpenetrated SALEM-14 was formed and converted catalytically into PAH-MOF-1 with polycyclic aromatic hydrocarbon (PAH) pillars. The metal-organic framework in SALEM-14 prevents "intermolecular" olefin metathesis from occurring between the pillars in the presence of the first generation Hoveyda-Grubbs catalyst, while favoring the production of a PAH, which can be released from the framework under acidic conditions in dimethylsulfoxide.
A practical synthesis of 4-chloro-3-(hydroxymethyl)pyridine by regioselective one-pot lithiation/formylation/reduction of 4-chloropyridine
Albanese, Domenico,Penso, Michele,Zenoni, Maurizio
, p. 1294 - 1296 (1999)
4-Chloro-3-(hydroxymethyl)pyridine was prepared and isolated as its hydrochloride in 85% yield from 4-chloropyridine by formylation with dimethylformamide of the corresponding 3-lithium salt, followed by in situ reduction of the resulting 4-chloro-3-formylpyridine through a crossed- Cannizzaro reaction with aqueous formaldehyde.

supporting information, p. 49 - 52 (2013/02/23)
The synthesis of new 5H-pyridobenzazepine and 5H-dipyridoazepine compounds using as key step a palladium-catalyzed amination-cyclization reaction is reported. By choosing an appropriate combination of ligands and reactants under standardized reaction conditions, N- and S-tricyclic products can be prepared in one step from the appropriate stilbenes.
