Inexpensive Radical Methylation and Related Alkylations of Heteroarenes
Huang, Qi,Zard, Samir Z.
supporting information, p. 1413 - 1416 (2018/03/09)
A simple method for the introduction of a methyl and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-methyl pyrrolidone in a microwave oven.

The regiodivergent C-H borylation of 2,5-disubstituted heteroarenes with bis(pinacolato)diboron was achieved by using iridium catalysts formed in situ from [Ir(OMe)(cod)]2/dtbpy (cod=1,5-cyclooctadiene, dtbpy: 4,4′-di-tert-butyl-2,2′-bipyridine) or [Ir(OMe)(cod)]2/2 AsPh3. When [Ir(OMe)(cod)]2/dtbpy was used as the catalyst, borylation at the 4-position proceeded selectively to afford 4-borylated products in high yields (dtbpy system A). The regioselectivity changed when the [Ir(OMe)(cod)]2/2 AsPh3 catalyst was used; 3-borylated products were obtained in high yields with high regioselectivity (AsPh3 system B). The regioselectivity of borylation was easily controlled by changing the ligands. This reaction was used in the syntheses of two different bioactive compound analogues by using the same starting material. Minor adjustments, major differences: The regiodivergent C-H borylation of 2,5-disubstituted heteroarenes with bis(pinacolato)diboron was achieved by using iridium catalysts formed in situ from [Ir(OMe)(cod)]2/dtbpy (cod=1,5-cyclooctadiene, dtbpy: 4,4'-di-tert-butyl-2,2'-bipyridine) or [Ir(OMe)(cod)]2/2 AsPh3 (see scheme).
Visible-light sensitization of vinyl azides by transition-metal photocatalysis

Irradiation of vinyl and aryl azides with visible light in the presence of Ru photocatalysts results in the formation of reactive nitrenes, which can undergo a variety of C-N bond-forming reactions. The ability to use low-energy visible light instead of UV in the photochemical activation of azides avoids competitive photodecomposition processes that have long been a significant limitation on the synthetic use of these reactions. Rock and pyrrole: Irradiation of vinyl and aryl azides with visible light in the presence of Ru photocatalysts results in the formation of reactive nitrenes, which can undergo a variety of C-N bond-forming reactions. The ability to use low-energy visible light instead of UV in the photochemical activation of azides (see picture) avoids competitive photodecomposition processes. Copyright

3,4-Dihydro-2H-pyrroles and 2,3,4,5-tetrahydropyridines are prepared by treatment of (E)-O-methylsulfonyloximes having an active methine group at γ- or δ-position with 1,8-diazabicyclo[5.4.0]undec-7-ene via SN2-type substitution on sp2 nitrogen atom of the oxime derivatives.
