Texto completo da fonteSince the pioneering work of Akiyama and Terada in 2004 on the use of chiral phosphoric acid as organocatalysts, a huge amount of efforts has been devoted to the development of C2-axially chiral catalysts. Despite being successful in many transformations, the potential industrial development of this family of catalysts is hampered by a tedious multisteps synthetic access. In this context, the synthesis of easily accessible, configurationally stable P-stereogenic and original thiophosphi(o)nic acid catalysts was achieved and, as a preliminary experiment, they were engaged in an enantioselctive Pictet-Spengler reaction showing very encouraging results. In a second project, we tried to develop a new organocatalyzed enantioselective arylation reaction to obtain new coumarin-aryl atropisomers with promising results. Then, we aimed at developing a new method for the stereoselective synthesis of furans displaying two atropisomericaxis by chirality conversion strategy. We first performed the enantioselective synthesis of dihydrofurans by a heteroannulation. Very promising results were obtained with two types of arylacetyl nucleophiles activated by a bifonctionnal organocatalyst or by a catalytic complex of Ni(II) and chiral diamine.The synthesis of configurationnally stable (hetero) [4]helicenes constitutes a synthetic challenge since these molecules rapidly racemizeat room temperature. Two configurationnally stable hetero [4]pseudo-helicenes were obtained by Au-promoted alkynes intramolecular hydroarylation. We also tried to synthesize [4]helicenic compounds by Brønsted acid organocatalized double Friedel-Crafts reaction. However, the desired products could not be isolated

The chemistry of palladium has been developed in recent years as a powerful method to promote the formation of carbon-carbon bond. In this thesis, we describe the palladium-catalyzed cross-coupling, hydroarylation and ring expansion-addition reactions of aryl iodides with alkynes. Firstly, the reaction of aryl iodides with 2-alkynylbenzonitriles in the presence of Pd(PPh3)4 and NaOCH3 in methanol provided 3-diarylmethylideneisoindoles and 3,4-disubstituted isoquinolines via the cross-coupling and cyclization reaction. Reaction of 2-ethynylbenzonitrile with 2.5 equiv. of iodobenzene gave 3-diphenylmethylideneisoindole in 45% yield along with the minor monocoupled adduct 3-phenylmethylideneisoindole in 6% yield. Secondly, treatment of aryl iodides with disubstituted alkynes in the presence of Pd(OAc)2 and sodium methoxide in methanol afforded trisubstituted ethylenes. The hydrogenolysis of the organopalladium is proposed through β-hydride elimination of the palladium methanolate intermediate. Finally, the one-step synthesis of 2-diarylmethylidenecyclopentanone derivatives was achieved by the palladium-catalyzed tandem rearrangement and addition of 1-ethynylcyclobutanols with aryl iodides. When the catalyst (Pd(OAc))2 was replaced by Pd(dba)2, Pd(OCOCF3)2 or Pd(CH3CN)2Cl2 under the same reaction conditions, 2-diarylmethylidenecyclopentanones were obtained in modest yields. Triethyl amine (Et3N) was the best base, and other bases, such as K2CO3、Na2CO3 and NaOAc, were less effective.
