Two complementary regiodivergent Pd-catalyzed arylations of the lithium salts of 6-membered cyclic allylboronates are reported.
Metal-free selective C–H thiolation of quinoline, including trifluoromethyl thiolation, aryl thiolation, alkyl thiolation and phenyl selenylation, using N-arylmethyl activation strategies is reported and is applicable to quinoline-based biologically active complex molecules.
A practical approach for preparing 3,4-fused 2-quinolones has been disclosed. The Rh(III)-catalyzed highly selective alkenyl C–H activation/annulation of 4-amino-2-quinolones was achieved via an unprecedented reversible alkyne insertion.
A novel and effective RhIII- and PdII-controlled switchable C–H alkenylation of 2-pyridylthiophenes with alkenes is realized.
This review article highlights the diverse ways in which recent developments in the areas of photocatalysis and visible light photochemistry are impacting synthetic carbohydrate chemistry.
