Hydrogenation of BF2 complexes with 1,3-dicarbonyl ligands

The catalytic hydrogenation (H2, Pd/C) of a set of BF2 complexes with a 1,3-dicarbonyl structural unit leading to monocarbonyl compounds has been studied. The transformation presented is general for the aryl-substituted derivatives and occurs under mild conditions (H2, 1 bar, 25 C) in methanol or THF.

Boronate urea activation of nitrocyclopropane carboxylates

Boronate ureas operate as catalysts for the activation of nitrocyclopropane carboxylates in nucleophilic ring-opening reactions. A variety of amines were found to open the urea-activated nitrocyclopropane carboxylates, generating highly useful nitro ester building blocks in good yields. Standard manipulations allow access to a wide range of valuable compounds from the ring-opened products with direct applications in bioactive target synthesis.

New inhibitors of the malaria aspartyl proteases plasmepsin I and II

New inhibitors of plasmepsin I and II, the aspartic proteases of the malaria parasite Plasmodium falciparum, are described. From paralell solution phase chemistry, several reversed-statine type isostere inhibitors, many of which are aza-peptides, have been prepared. The synthetic strategy delivers the target compounds in good to high overall yields and with excellent stereochemical control throughout the developed route. The final products were tested for their plasmepsin I and II inhibiting properties and were found to exhibit modest but promising activity. The best inhibitor exhibits Ki values of 250 nM and 1.4 muM for Plm I and II, respectively.

alpha-Substituted norstatines as the transition-state mimic in inhibitors of multiple digestive vacuole malaria aspartic proteases

The impact of moving the P1 side-chain from the beta-position to the alpha-position in norstatine-containing plasmepsin inhibitors was investigated, generating two new classes of tertiary alcohol-comprising alpha-benzylnorstatines and alpha-phenylnorstatines. Twelve alpha-substituted norstatines were designed, synthesized and evaluated for their inhibitory potencies against plasmepsin II and the plasmepsin IV orthologues (PM4) present in the digestive vacuole of all four Plasmodium species causing malaria in man. New synthetic routes were developed for producing the desired alpha-substituted norstatines as pure stereoisomers. The best compounds provided Ki values in the nanomolar range for all PM4, with a best value of 110 nM in PM4 from Plasmodium ovale. In addition, excellent selectivity over the closely related human aspartic protease Cathepsin D was achieved. The loss of affinity to Plasmodium falciparum PM4, which was experienced upon the move of the P1 substituent, was rationalized by the calculation of inhibitor-protein binding affinities using the linear interaction energy method (LIE).

Enantioselective syntheses of beta-amino alcohols catalyzed by recyclable chiral Fe(III) metal complex

An efficient asymmetric desymmetrization of meso-epoxides with anilines catalysed by a series of simple and environmentally benign in situ generated Fe(iii) complexes based on chiral tridentate ligands L1-L7 with achiral and chiral linkers (methylene, piperazine, R/S BINOL and diethyl tartrate) was carried out at rt. The in situ generated iron metal complex based on ligand L5a emerged as improved (low catalyst loading) catalyst for asymmetric desymmetrization of meso-epoxides with anilines giving high enantioselectivity (up to 99%) and high yield (95%) of enantiopure beta-amino alcohols in 14 h. While excellent results for ARO of cyclic as well as aliphatic epoxides with anilines was achieved with in situ generated complex from the ligand L4h and Fe(iii) chloride, the catalyst was recoverable and recyclable (five times) with retention of its performance.

Reusable chiral bis(oxazoline)-copper complexes immobilized by donor-acceptor interactions on insoluble organic supports

Heterogeneous asymmetric Diels-Alder reactions between cyclopentadiene and 3-but-2-enoyl-oxazolidin-2-one were efficiently promoted by reusable chiral bis(oxazoline)-copper catalysts, immobilized through charge transfer interactions with trinitrofluorenone, that was covalently grafted on Merrifield resins. The modified support was also used for the synthesis of both enantiomers of the target product, thanks to the non-covalent anchoring of the catalyst that allowed its easy removal and exchange.

Oxazolines as Dual-Function Traceless Chromophores and Chiral Auxiliaries: Enantioselective Photoassisted Synthesis of Polyheterocyclic Ketones

2-(o-Amidophenyl)oxa- and -thiazolines undergo excited-state intramolecular proton transfer (ESIPT), generating aza-o-xylylenes capable of intramolecular [4+2] and [4+4] cycloadditions with tethered unsaturated pendants. Facile hydrolysis of the primary photoproducts, spiro-oxazolidines and thiazolidines, under mild conditions unmasks a phenone functionality. Variations in linkers allow for access to diverse core scaffolds in the primary photoproducts, rendering the approach compatible with the philosophy of diversity-oriented synthesis. Chiral oxazolines, readily available from the corresponding amino alcohols, yield enantioenriched keto-polyheterocycles of complex topologies with enantiomeric excess values up to 90%.
