Chirality sensing of amines, diamines, amino acids, amino alcohols, and alpha-hydroxy acids with a single probe

A stereodynamic probe for determination of the absolute configuration and enantiomeric composition of chiral amines, diamines, amino alcohols, amino acids, and alpha-hydroxy carboxylic acids is described. The chirality sensing is based on spontaneous asymmetric transformation of the first kind with stereolabile binaphtholate boron and zinc complexes. The substrate binding and chiral amplification processes yield a distinctive chiroptical sensor output at high wavelength that can be used for rapid and accurate ee detection of minute sample amounts.

Synthesis of new chiral auxiliaries for 6pi-azaelectrocyclization: 4- and 7-alkyl substituted cis-1-amino-2-indanols

The synthesis of new chiral auxiliaries, 7-alkyl substituted cis-1-amino-2-indanol derivatives, was established by the Diels-Alder reaction of 1-substituted dienes with cyclopentenone followed by the asymmetric epoxidation of the resulting indene derivatives and then the Ritter reaction. These bulky cis-aminoindanol derivatives are very effective as chiral auxiliaries and nitrogen sources in the asymmetric 6pi-azaelectrocyclization. The corresponding 4-alkyl derivative was also prepared using a similar method.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model.

The influence of ligand bite angle on the enantioselectivity of copper(II)-catalysed Diels-Alder reactions

Novel spirobis(oxazolines) provide excellent levels of stereocontrol in copper-catalysed Diels-Alder reactions; the larger the ligand bite angle the higher the enantioselection (up to 98.4% ee).

Potent and selective aggrecanase inhibitors containing cyclic P1 substituents

Anti-succinate hydroxamates with cyclic P1 motifs were synthesized as aggrecanase inhibitors. The N-methanesulfonyl piperidine 23 and the N-trifluoroacetyl azetidine 26 were the most potent aggrecanase inhibitors both having an IC50=3 nM while maintaining >100-fold selectivity over MMP-1, -2, and -9. The cyclic moieties were also capable of altering in vivo metabolism, hence delivering low clearance compounds in both rat and dog studies as shown for compound 14.

Facile Access to Optically Active 2,6-Dialkyl-1,5-Diazacyclooctanes

The chiral substituted 1,5-diazacyclooctane (1,5-DACO) is of considerable importance and has attracted attention from a wide range of fields due to their unique chemical and biological properties. Despite the application potential, further study has not been optimized due to difficulties in their synthetic accessibility. Here, we report that the 1,5-DACO bearing a chiral auxiliary obtained from the formal [4+4] cycloaddition of N-alkyl-alpha,beta-unsaturated imines can be further derivatized by nucleophilic alkylation to give various chiral substituted 1,5-DACO derivatives. The removal of the chiral auxiliary was effectively carried out using hydrogenation over Pearlman’s catalyst. This methodology allows the production of a broad range of unprecedented optically active 2,6-dialkyl-1,5-DACO, which could not be accessed by other methods.

Lewis acid-catalyzed asymmetric diels-alder reactions using chiral sulfoxide ligands: chiral 2-(arylsulfinylmethyl)-1,3-oxazoline derivatives.

New chiral sulfoxide-1,3-oxazoline ligands have been developed as chiral ligands for Lewis acid-catalyzed asymmetric Diels-Alder reactions. The use of chiral sulfinyl 1,3-oxazoline ligands in copper(II)-catalyzed asymmetric Diels-Alder reactions provided an endo cycloadduct as a major product with moderate enantioselectivity. A rationale is proposed for the mechanism of the asymmetric induction.

Synthesis and activity of HIV protease inhibitors

We report here the synthesis and activity of HIV protease inhibitors. In the first stage hydrophobic compounds incorporating a ‘carba’ bond surrogate or a beta-homologated residue were synthesized. Secondly, we synthesized cyclic compounds in which we incorporated 2-quinoline carboxylic acid in the P3 position and the amino-hydroxyindane moiety in the P’3. The last part of this work was dedicated to a structure/activity study of a peptide substrate. These modifications allowed us to work up the synthesis of new pseudopeptide bonds: amino-amide and hydroxy-amide. Compounds with activity in the micromolar range were actually a starting point for the synthesis of new protease inhibitors.

Polyfunctional Bis-Lewis-Acid-/Bis-Triazolium Catalysts for Stereoselective 1,4-Additions of 2-Oxindoles to Maleimides

Achieving enzyme-like catalytic activity and stereoselectivity without the typically high substrate specificity of enzymes is a challenge in the development of artificial catalysts for asymmetric synthesis. Polyfunctional catalysts are considered to be a promising tool for achieving excellent catalytic efficiency. A polyfunctional catalyst system was developed, which incorporates two Lewis acidic/Br¡ãnsted basic cobalt centers in combination with triazolium moieties that are crucial for high reactivity and excellent stereoselectivity in the direct 1,4-addition of oxindoles to maleimides. The catalyst is assembled through click chemistry and is readily recyclable through precipitation by making use of its charges. Kinetic studies support a cooperative mode of action. Diastereodivergency is achievable with either Boc-protected or unprotected maleimide.

Design, asymmetric synthesis, and evaluation of pseudosymmetric sulfoximine inhibitors against HIV-1 protease

The HIV-1 protease is a validated drug target for the design of antiretroviral drugs to combat AIDS. We previously established the sulfoximine functionality as a valid transition state mimetic (TSM) in the HIV-1 protease inhibitors (PI) design and have identified a lead pseudosymmetric compound with nanomolar enzymatic inhibitory activity. Here, we report the asymmetric synthesis of this compound and its application in the synthesis of sulfoximine-based peptidomimetic HIV-1 protease inhibitors. Molecular modeling revealed the potential mode of binding of the sulfoximine inhibitor as a TSM. The predicted absolute binding free energies suggested similar inhibitory effect as observed in our enzymatic inhibitory studies.
