Abstract:
An expedient desymmetrization of 3,5-dimethyl-4-alkoxyglutaric anhydrides to access anti,anti-polypropionates is described. The previously unknown anhydrides are rapidly assembled from readily available precursors. A Rh(I)·t-BuPHOX catalyst system was found to provide good yield and high selectivities. With these conditions, the trisubstituted anhydrides were desymmetrized with various alkyl zinc reagents to provide synthetically useful enantioenriched anti,anti-2,4-dimethyl-3-hydroxy-δ-ketoacids. An identical catalyst system also affords access to syn,syn-stereotriads as well as a partial kin

Abstract:
Our recent progress toward the synthesis of the furanocembranolide lophotoxin (1) is disclosed. Strategies for the stereoselective incorporation of the C13 stereocenter by a catalytic desymmetrization of a cyclic meso-anhydride, as well as a novel 1,6-addition reaction of organocuprates to unsaturated [1,3]dioxin-4-ones are discussed. Preliminary results on the development of a rhodium-catalyzed asymmetric 1,6-addition reaction are also mentioned. Finally, modifications of a previously reported transition-metal-catalyzed cyclization reaction involving α-propargyl β-keto esters allow furan ring

We disclose our synthetic studies on bilobalide, which features a Diels–Alder reaction of a cyclic anhydride to form two contiguous quaternary carbon centers, desymmetrization of a symmetric diol, and construction of a cyclic acetal under acidic conditions with inversion of configuration at an allylic position.

Abstract:
For the first time, chiral sulfoximine derivatives have been applied as asymmetric organocatalysts. In combination with a thiourea-type backbone the sulfonimidoyl moiety leads to organocatalysts showing good reactivity in the catalytic desymmetrization of a cyclic meso-anhydride and moderate enantioselectivity in the catalytic asymmetric Biginelli reaction. Straightforward synthetic routes provide the newly designed thiourea-sulfoximine catalysts in high overall yields without affecting the stereohomogeneity of the sulfur-containing core fragment.

Abstract:
Organomagnesium reagents are among the most important reagents in organic chemistry because of their great utility in forming carbon–carbon bonds. Although most enantioselective reactions using these organometallics involve transmetalation, the past decade has witnessed impressive advances in direct chiral-ligand-mediated reactions of organomagnesiums­.

Abstract:
Cyclitols are of great importance due to their biological activities playing a crucial role in living organisms as well as their synthetic usefulness in the synthesis of other natural compounds or pharmaceuticals. In this study, new synthetic strategies leading to the aminocyclitols were investigated. The synthesis of aminoconduritol and aminoinositol derivatives (173 and 174) were achieved starting from easily available compound, 7-oxa-bicyclo[2.2.1]hept-5-ene-2,3-dicarboxylic anhydride (166) obtained from the Diels-Alder reaction of furan and maleic anhydride.

Abstract:
Depuis une quinzaine d’années, les polymères chiraux sont utilisés dans de nombreuses applications, comme phases stationnaires pour la séparation d’énantiomères ou encore en tant que catalyseurs en synthèse asymétrique. Aux vues de ces intérêts grandissants, de nombreuses méthodes ont émergé afin de les synthétiser. Nous nous sommes concentrés sur des méthodes organocatalytiques originales de synthèse de polymères chiraux par réaction de polyaldolisation et par désymétrisation de bis-anhydrides. Nous avons ainsi développé des processus de désymétrisation itératifs et ainsi généré une chiralité
