Texto completoThis PhD research aims to achieve challenging C(sp³)-C(sp²) and C(sp³)-C(sp³) bond formations through Suzuki-Miyaura and Kumada cross-couplings using newly-designed iron-based catalysts, with an emphasis on their potential for synthetic applications. This work also focuses on achieving efficient and selective 1,2-dicarbofunctionalization of unactivated alkenes promoted by these catalysts. Chapter 1 primarily introduces the early discoveries of iron-mediated cross-couplings and the development of iron-based catalysts in Suzuki-Miyaura and Kumada cross-couplings, covering C(sp²)-C(sp²), C(sp²)-C(sp³), and C(sp³)-C(sp³) bond formations. The design of bespoke ligand and mechanistic investigations have played a crucial role in the development of this field. The following section introduces the state-of-the-art in earth-abundant metal-catalyzed 1,2-dicarbofunctionalization of olefins, highlighting strategies developed to overcome undesired side reactions. Chapter 2 covers the Suzuki-Miyaura reaction, which has gained widespread use due to its broad applicability, along with the stability, availability, and low toxicity of organoboron reagents. Most Suzuki-Miyaura couplings (SMC), both in academia and industry, are dominated by palladium and nickel catalysts. Recently, iron has garnered significant attentions due to its earth abundance and environmentally friendly nature. Despite the crucial role of iron in offering more sustainable catalysis for Suzuki-Miyaura coupling, iron-catalyzed SMC involving sp³-hybridized systems remains rare and faces significant scope limitations. This chapter reports on the development of a versatile, well-defined iron(II) catalyst that successfully facilitated C(sp3)-C(sp2) and C(sp3)-C(sp3) SMC of alkyl halide electrophiles with (hetero)aryl boronic esters and alkyl borane nucleophiles, respectively. These couplings were carried out under mild reaction conditions, exhibited broad functional group compatibility - including various medicinally important N-, O-, and S-based heterocycles. Primary, secondary alkyl halides (Br, Cl, I), and tertiary alkyl chlorides, as well as electron-neutral, electron-rich, and electron-poor boronic esters, alongside 1° and 2° alkyl boranes all were tolerated with high to excellent yields. Greener solvents were used in the synthesis of key intermediates relevant to pharmaceuticals and potential drug candidates with high yields, demonstrating significant potential for large-scale industrial production. Chapter 3 introduces the application of Suzuki-Miyaura cross-coupling in the three-component 1,2-alkylarylation of unactivated olefins, using a well-defined iron(II) catalyst. This method facilitates the formation of two carbon-carbon bonds in a single synthetic step and represents the first example of combining Suzuki-Miyaura cross-coupling and 1,2-functionalization of unactivated alkenes, selectively yielding the desired 1,2-alkylarylation product. Although the current methodology is limited by the requirement for an excess of olefins (10 equiv.) and electron-donating boronic esters, the use of boron reagents demonstrates a potential for broader synthetic applications. Chapter 4 extends the application of the iron(II) catalyst developed in Chapters 2 and 3, demonstrating its remarkable efficacy in catalyzing the Kumada cross-coupling reaction between C(sp³)-hybridized alkyl halides and either C(sp²)- or even C(sp³)-hybridized organomagnesium reagents under mild conditions. This achievement underscores the broad versatility of this catalyst in facilitating the coupling of diverse carbon centers, including both sp² and sp³ hybridizations, without requiring harsh conditions

In this thesis, we are interested in converting endo formyl [2.2.1]bicyclic carbinols into a bicyclic [3.2.1]α-amino ketone. The consecutive condensation and ring expansion reactions of carbinols 47 and 71 are the most important steps. Compound 47 and compound 71 reacted with various kinds of primary amine which are N-nucleophiles, via intramolecular rearrangement to give ring expansion reaction products. The reaction had proved to be highly chemoselective、regioselective and stereoselective. The bicyclic [3.2.1]α-amino ketone is the final product. The alkyl or aryl group of primary amines might be methyl、ethyl、other alkyl, para-substituted electron donating or electron withdrawing aryl group. The mechanisms for the reactions of carbinols 47 and 71 with various primary amine are also discussed.

Abstract The acetylenic compounds are important building block in the fields of pharmaceutical chemistry and organic synthesis. The transition metal catalyzed coupling reaction of terminal alkynes with aryl halides has become one of the most important methods for preparing functionalized alkynes. Palladium and copper co-catalyzed system is well known as Sonogashira reaction, however, palladium is not only expensive but also highly toxic. Thus, develop the system by using copper as the sole metal source has gain much attention in recent years. The first part of this thesis, we report a highly efficient catalytic system employs the combination of Cu2O (1 mol %) with bisphosphine ligand, giving the products in good to excellent yields. Recently, aryl vinyl sulfides have been reported as drug candidates against drugresistant strains of tuberculosis and anthrax, in addition to many other drug-resistant Gram-positive bacteria. Addition of thiols to alkynes through a radical pathway is a common way to prepare these compounds, however, this method will produce the undesired regioisomers at the same time. Transition metals including palladium, cobalt and copper have been reported for coupling reaction of thiols with vinyl halides. The second part of this thesis, we report the first iron-catalyzed coupling reaction of thiols with vinyl halides in the presence of a bisphosphine ligand, giving the aryl vinyl sulfide in good yields.
