Chapter 1 describes the development of chiral biphenyl-derived phosphepines and their application as catalysts for an asymmetric [4 + 1] annulation to form functionalized cyclopentenes bearing a non-spirocyclic quaternary stereocenter. Additional studies demonstrate the synthetic utility of the cyclopentene products for further stereoselective functionalization and provide insight into the mechanism of the reaction. Chapter 2 describes the development of photoinduced, copper-catalyzed C-N couplings between aromatic nitrogen heterocycles (i.e., indole, benzimidazole, imidazole, and carbazole) and aryl, alkenyl, and alkynyl halides. These reactions utilize an inexpensive catalyst (Cul, without an additional ligand) and proceed at unusually low temperature for Ullmann coupling processes with these heterocycles (room temperature). Additional studies probe the selectivity of the reaction with respect to both the nucleophilic and the electrophilic coupling partner. Chapter 3 details progress towards developing a method for asymmetric, intermolecular y additions of oxygen nucleophiles to alkynoates using a chiral phosphine catalyst. Conditions are presented that effectively couple alkynoates bearing an aryl substituent at the y position with a variety of alcohols in good yield and high ee. Future efforts will be focused on expanding the scope of this process and conducting experiments to gain insight into the reaction mechanism.

Texto completoThe work described in this manuscript involved the reactivity of keto-3-keto-alkynoates and and keto-sulfonamides. Keto-3-alkynoates led to bi- or tricyclic allenoates in the presence of a catalytic amount of cesium carbonate. Cyclization proceeds in a totally stereoselective manner in the case of the two-carbon linker chain. A one-pot reaction starting from alkynyl ketones afforded tricyclic fused ring systems with good yields. Enantiomerically enriched, oxidized, conjugated or non-conjugated jasmonate derivatives were obtained through 3-alkynoates, in particular (-)-12-COOH-JA and (-)-12-COOH-JA-Ile found in wounded leaves. The availability of those synthetic compounds allowed deeper exploration of the complex regulation of JA-Ile hormone homeostasis and unraveled an oxidative and a hydrolytic pathway. Aza-bicyclo[n.m.1]alkanone frameworks could be obtained when keto-sulfonylynamides were treated under silver catalysis. This formal Conia-ene reaction was compatible with various cycloalkanones, as well as a wide range of functionalized ynamides

In the first part of this thesis, we report the synthesis of thioether with highly regioselectivity. The reaction proceeded through iron-catalyzed para-selective bromination followed by copper/oxalic diamide-catalyzed C-S bond cross-coupling reaction, 24 examples were reported up to 91% yield. In the second part of this thesis, a tandem oxidative reaction of alkynoates with aryl disulfides for the synthesis of vinyl sulfides via radical process has been described. The reaction proceeds through arylthiolation of a C-C triple bond, 1,4-aryl migration, and decarboxylation under metal-free conditions. This process demonstrates a multistep radical cascade reaction and also represents a strategy of direct decarboxylation of esters.
