Full textThis thesis work is consecrated to the study of palladium-catalyzed [3+2]-annulation and domino reactions. First, a new domino sequence was developed, which involves the reaction between cyclic α,β-unsaturated-γ-oxy-carbonyl derivatives and resonance-stabilized acetamides. The resulting bicyclic pyrrolidin-2-ones were generated through an intermolecular Pd-catalyzed allylation followed by an intramolecular aza-Michael reaction sequence. An asymmetric version was also achieved, obtaining up to 60% ee. A new Pd-catalyzed [allylation / aza-Michael / keto α-arylation] (ALAMAR) triple domino sequence was also accomplished, which allows the selective one-pot formation of fused tricyclic systems. Lastly, two selective and complementary domino transformations have been achieved, which allow to perform C−C/O−C or C−C/C−C [3+2]-annulations at will. These transformations occur through an intermolecular Pd-catalyzed C-allylation / intramolecular O- or C-1,4-addition sequence, respectively

-bromo acetophenones at room temperature in the presence of different bases were described to afford two diastereomeric epoxy phosphonates in good yields and high diastereoselectivities. The diastereoselectivity of this reaction is easily controlled by changing the base. Accordingly, changing the base from Cs2CO3 to DBU changes the diatereomeric ratio (trans/cis) from 5/3 to 9/1. Furthermore, the treatment of trans isomer with DBU shows a complete conversion to the corresponding cis isomer. Additionally, these highly functionalized epoxyphosphonates are shown to be useful intermediates to give several reactions

(Trialkylsilyl)vinylketenes ("(TAS)vinylketenes") and (trialkylsilyl)arylketenes ("(TAS)- arylketenes") function as versatile four-carbon building blocks for the synthesis of carbocyclic and heterocyclic compounds. A new [4 + 1] annulation strategy for the synthesis of substituted 2-indanones, based on the reaction of TAS-arylketenes with trimethylsilyl diazomethane, has been developed. In addition, a new class of carbenoid reagents for our previously reported [4 + 1] cyclopentenone annulation has been identified. Studies have shown that the reaction of a- benzotriazolyl organolithium compounds (prepared via metallation of readily available N- substituted benzotriazole derivatives) with (TAS)vinylketenes generates dienolate intermediates which cyclize to form cyclopentenones. Most cases of the annulation proceed with a high level of diastereoselectivity, and deliver highly substituted and functionalized 2-silylcyclopentenones in good yield. Furthermore, the vinylsilane moiety incorporated in the [4 + 1] annulation products provides a useful handle for further synthetic transformations. Preliminary studies focused on elaboration of the cyclopentenone products have laid the groundwork for future applications of this [4 + 1] annulation methodology.
