Diazines VII. A new synthetic route to the pyridazine antidepressant, minaprine using directed ortho metalation and Suzuki cross coupling reactions

A new synthetic route has been developed for minaprine.The synthesis is based upon two reactions recently studied on pyridazine: metalation and cross coupling with transition metals.Some different routes have been tested starting from 3,6-dichloropyridazine.The best results were obtained by coupling phenylboronic acid with 3-chloro-6-methoxypyridazine then by metalating 3-methoxy-6-phenylpyridazine and reacting the lithio derivatives with methyl iodide. 3-Methoxy-4-methyl-6-phenylpyridazine was obtained.After hydrolysis of the ether moiety, chlorination and substitution by the amine, minaprine was obtained with an overall yield of 36percent.Keywords – pyridazine / metalation / cross-coupling

Use of N-Protected Amino Acids in the Minisci Radical Alkylation

(Equation presented) The Minisci radical alkylation has been demonstrated on a range of commercially available glycine derivatives and proceeds in good to high yield. When extending the reaction to other amino acids, competitive oxidation of the initially formed radical was overcome by using the phthalimide protecting group.

A large scale synthesis of 3-chloro-5-methoxypyridazine

A large scale synthesis of 3-chloro-5-methoxypyridazine was developed (18 moles) that relies on the protection of the pyridazinone nitrogen of 4,5-dichloro-3(2H)-pyridazinone as the tetrahydropyranyl derivative 2. The 5-chloro position of the protected pyridazinone was selectively displaced with methoxide to give 3 followed by catalytic hydrogenation of the 4-chloro group to give 4. Removal of the protecting group with acid followed by phosphorous oxychloride treatment gave the target compound 6 in good yield. This route is superior to the previously described synthesis of this compound.

Olefin cross-metathesis/Suzuki-Miyaura reactions on vinylphenylboronic acid pinacol esters

A series of alkenyl phenylboronic acid pinacol esters has been synthesized via an olefin cross-metathesis reaction of vinylphenylboronic acid pinacol ester derivatives. After catalytic hydrogenation, the resulting boronates were coupled via a microwave-mediated Suzuki-Miyaura reaction to afford a library of biarylethyl aryl and biarylethyl cycloalkyl derivatives. A complementary reaction sequence involved an initial Suzuki-Miyaura coupling.

Influence of Fluorination on the Conformational Properties and Hydrogen-Bond Acidity of Benzyl Alcohol Derivatives

The effect of fluorination on the conformational and hydrogen-bond (HB)-donating properties of a series of benzyl alcohols has been investigated experimentally by IR spectroscopy and theoretically with quantum chemical methods (ab initio (MP2) and DFT (MPWB1K)). It was found that o-fluorination generally resulted in an increase in the HB acidity of the hydroxyl group, whereas a decrease was observed upon o,o?-difluorination. Computational analysis showed that the conformational landscapes of the title compounds are strongly influenced by the presence of o-fluorine atoms. Intramolecular interaction descriptors based on AIM, NCI and NBO analyses reveal that, in addition to an intramolecular OH…F interaction, secondary CH…F and/or CH…O interactions also occur, contributing to the stabilisation of the various conformations, and influencing the overall HB properties of the alcohol group. The benzyl alcohol HB-donating capacity trends are properly described by an electrostatic potential based descriptor calculated at the MPWB1K/6-31+G(d,p) level of theory, provided solvation effects are taken into account for these flexible HB donors.
