Dinucleating Ligand Platforms Supporting Indium and Zinc Catalysts for Cyclic Ester Polymerization

The synthesis of the first alkoxide-bridged indium complex supported by a chiral dinucleating ligand platform (1), along with its zinc analogue (2), is reported. Both complexes are synthesized in a one-pot reaction starting from a chiral dinucleating bis(diamino)phenolate ligand platform, sodium ethoxide, and respective metal salts. The dinucleating indium analogue (7) based on an achiral ligand backbone is also reported. Indium complexes bearing either the chiral or achiral ligand catalyze the ring-opening polymerization of racemic lactide (rac-LA) to afford highly heterotactic poly(lactic acid) (PLA; Pr > 0.85). The indium complex bearing an achiral ligand affords essentially atactic PLA from meso-LA. The role of the dinucleating ligand structure in catalyst synthesis and polymerization activity is discussed.

Asymmetric isomerization of omega-hydroxy-alpha,beta-unsaturated thioesters into beta-mercaptolactones by a bifunctional aminothiourea catalyst

We present a novel methodology for the asymmetric synthesis of beta-mercaptolactones via isomerization of omega-hydroxy-alpha,beta- unsaturated thioesters by means of a bifunctional aminothiourea catalyst. The catalyst interacts with the substrate through the cooperative action of both a covalent bond at the amino group and noncovalent bonding at the thiourea group. The potential for an enantiodivergent synthesis could also be demonstrated by carrying out the reaction in a different solvent system.

Cooperative assistance in bifunctional organocatalysis: Enantioselective mannich reactions with aliphatic and aromatic imines

Hold them tight: Guided by X-ray structures, bifunctional thiourea catalysts containing an activating intramolecular hydrogen bond were redesigned.

Doubly stereocontrolled asymmetric Michael addition of acetylacetone to nitroolefins promoted by an isosteviol-derived bifunctional thiourea

A novel class of chiral bifunctional thioureas bearing a chiral lipophilic beyerane scaffold and a tertiary amino group was designed and prepared. The thioureas were proven to be effective for catalyzing the doubly stereocontrolled asymmetric Michael addition between acetylacetone and nitroolefins. The corresponding adducts were obtained in high yields (up to 95%) and with good to excellent enantioselectivities (up to 97%). In addition, the reaction of tert-butyl acetoacetate and trans-beta-nitrostyrene also proceeded smoothly with good enantioselectivity.

Stereoselective reaction of 2-carboxythioesters-1,3-dithiane with nitroalkenes: An organocatalytic strategy for the asymmetric addition of a glyoxylate anion equivalent

An efficient organocatalytic methodology has been developed to perform the stereoselective addition of 2-carboxythioesters-1,3-dithiane to nitroalkenes. Under mild reaction conditions gamma-nitro-beta-aryl-alpha-keto esters with up to 92% ee were obtained, realizing a formal catalytic stereoselective conjugate addition of the glyoxylate anion synthon. The reaction products are versatile starting materials for further synthetic transformations; for example, the simultaneous reduction of the nitro group and removal of the dithiane ring was accomplished, allowing the preparation of a GABAB receptor agonist baclofen.

Anion-pi Catalysis on Fullerenes

Anion-pi interactions on fullerenes are about as poorly explored as the use of fullerenes in catalysis. However, strong exchange-correlation contributions and the localized pi holes on their surface promise unique selectivities. To elaborate on this promise, tertiary amines are attached nearby. Dependent on their positioning, the resulting stabilization of anionic transition states on fullerenes is shown to accelerate disfavored enolate addition and exo Diels-Alder reactions enantioselectively. The found selectivities are consistent with computational simulations, particularly concerning the discrimination of differently planarized and charge-delocalized enolate tautomers by anion-pi interactions. Enolate-pi interactions on fullerenes are much shorter than standard pi- pi interactions and anion-pi interactions on planar surfaces, and alternative cation-pi interactions are not observed. These findings open new perspectives with regard to anion-pi interactions in general and the use of carbon allotropes in catalysis.
