Studies Clinical Microbiology, Research Journal of Medical Sciences, and Cell and Molecular Biology of Medicinal and Aromatic Plants. Radical cyclization reactions are organic chemical transformations that yield cyclic products through radical intermediates. They usually proceed in three basic steps: selective radical generation, radical cyclization, and conversion of the cyclized radical to product. Zunächst arbeitete Giese auf dem Gebiet der Kinetik und Selektivität komplexer organischer Reaktionen und führte radikalische (C-C)-Verknüpfungen als Synthesemethode ein.

Studied the influence of activation entropies on the selectivity of organic reactions, and developed the isoselective relationship. Contributed to the understanding of radical reactions, and developed a modern, stereoselective synthethis method (Giese reaction). An efficient cobalt-catalyzed difluoroalkylation/Giese radical conjugate cyclization manifold with various alkyne-tethered cyclohexadienones and halogenated fluorinating reagents was accomplished under remarkable mild reaction conditions, thus providing an expedient route to valuable fluorinated chromens. Introduction. Radical cyclization reactions produce mono- or polycyclic products through the action of radical intermediates. Because they are intramolecular transformations, they are often very rapid and selective.

With the use of an automated flow microreactor, flow reaction conditions for the Giese reaction were quickly optimized, and it was found that a reaction temperature of 70 °C in combination with a residence time of 10-15 minutes gave good yields of the desired addition products.

1 The reaction is very efficient when alkyl radicals (high‐lying SOMO) are added to electron‐deficient olefins (low‐lying LUMO), becoming a good alternative to the Michael reaction.

Pronunciation of Giese reaction with 1 audio pronunciation and more for Giese reaction. reactions were then set on theAldrich® Micro Photochemical Reactor overnight (16 h). Assay yields for desired product and remaining starting materials were determined by measuring its concentrations from a 50-70 mg aliquot of the reaction using standard HPLC techniques. Comparison of reaction rates under different light sources (Table S5). This type of reductive radical addition reaction, better known as the Giese reaction, was historically carried out most by using tributyltin hydride as the radical mediator . 2018-11-14 · Two named reactions of fundamental importance and paramount utility in organic synthesis have been reinvestigated, the Barton decarboxylation and Giese radical conjugate addition. In general, radical cyclization reactions comprise three basic steps: selective radical generation, radical cyclization, and conversion of the cyclized radical to the product. For the generation of the initial radical a broad variety of suitable precursors can be employed, such as halides, thio‐ and selenoethers, alcohols, aldehydes and hydrocarbons.
