The direct reductive amination of electron-deficient amines with aldehydes: The unique reactivity of the Re2O7 catalyst

An unprecedented direct reductive amination of electron-deficient amines such as Cbz-, Boc-, EtOCO-, Fmoc-, Bz-, ArSO2-, Ar2PO-, etc. protected amines with aldehydes is achieved using the Re2O 7 catalyst and silanes as the hydride source. Excellent regioselective mono-alkylation and chemoselective reductive-amination were observed.

Complete structure elucidation of shishididemniols, complex lipids with tyramine-derived tether and two serinol units, from a marine tunicate of the family Didemnidae

(Chemical Equation Presented) Two new serinolipid derivatives, shishididemniols A (1) and B (2), were isolated as antibacterial constituents of a tunicate of the family Didemnidae. The structure of 1 was elucidated by interpretation of spectral data and the application of the modified Mosher method to 1 and its suitable degradation products. Compound 2 was the chlorohydrin of 1. Compounds 1 and 2 exhibited antibacterial activity against fish pathogenic bacterium Vibrio anguillarum.

Stereoselective synthesis of pamamycin-607

A macrodiolide antibiotic pamamycin-607 was synthesized by joining two hydroxy acid components. Three cis-2, 5-disubstituted tetrahydrofuran rings in the molecule were stereoselectively prepared by radical cyclization reactions of beta-alkoxyvinyl ketone intermediates and a beta-alkoxymethacrylate substrate. The key step of the synthesis is characterized by the predominant threo product formation in the radical cyclization reaction of a beta-alkoxymethacrylate intermediate.

Calcium-catalyzed direct amination of pi-activated alcohols

A calcium-catalyzed direct amination of pi-activated alcohols with different nitrogen nucleophiles under very mild reaction conditions is presented. The high reactivity of the calcium catalyst allows for an efficient conversion of secondary and tertiary benzylic and allylic as well as tertiary propargylic alcohols. Nitrogen nucleophiles such as carbamates, tosylamides and anilines are readily alkylated at room temperature.

High potency and broad-spectrum antimicrobial peptides synthesized via ring-opening polymerization of alpha-Aminoacid-N-carboxyanhydrides

Antimicrobial peptides (AMPs), particularly those effective against methicillin-resistant Staphylococcus aureus (S. aureus) and antibiotic-resistant Pseudomonas aeruginosa (P. aeruginosa), are important alternatives to antibiotics. Typical peptide synthesis methods involving solid-phase sequential synthesis are slow and costly, which are obstacles to their more widespread application. In this paper, we synthesize peptides via ring-opening polymerization of alpha-amino acid N-carboxyanhydrides (NCA) using a transition metal initiator. This method offers high potential for inexpensive synthesis of substantial quantities of AMPs. Lysine (K) was chosen as the hydrophilic amino acid and alanine (A), phenylalanine (F), and leucine (L) as the hydrophobic amino acids. We synthesized five series of AMPs (i.e., P(KA), P(KL), P(KF), P(KAL), and P(KFL)), varied the hydrophobic amino acid content from 0 to 100%, and determined minimal inhibitory concentrations (MICs) against clinically important Gramnegative and Gram-positive bacteria and fungi (i.e., Escherichia coli (E. coli), P. aeruginosa, Serratia marcescens (S. marcescens), and Candida albicans (C. albicans). We found that P(K10F 7.5L7.5) and P(K10F15) show the broadest activity against all five pathogens and have the lowest MICs against these pathogens. For P(K10F7.5L7.5), the MICs against E. coli, P. aeruginosa, S. marcescens, S. aureus, and C. albicans are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 62.5 mug/mL, while for P(K10F15) the respective MICs are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 125 mug/mL. These are lower than the MICs of many naturally occurring AMPs. The membrane depolarization and SEM assays confirm that the mechanism of microbe killing by P(K10F 7.5L7.5) copeptide includes membrane disruption, which is likely to inhibit rapid induction of AMP-resistance in pathogens.

(S)-N-(5-Chlorothiophene-2-sulfonyl)-beta,beta-diethylalaninol a Notch-1-sparing gamma-secretase inhibitor

Accumulation of beta-amyloid (Abeta), produced by the proteolytic cleavage of amyloid precursor protein (APP) by beta- and gamma-secretase, is widely believed to be associated with Alzheimer’s disease (AD). Research around the high-throughput screening hit (S)-4-chlorophenylsulfonyl isoleucinol led to the identification of the Notch-1-sparing (9.5-fold) gamma-secretase inhibitor (S)-N-(5-chlorothiophene-2-sulfonyl)-beta,beta-diethylalaninol 7.b.2 (Abeta 40/42 EC50 = 28 nM), which is efficacious in reduction of Abeta production in vivo.

Chemoselective Copper-Catalyzed Ullmann-Type Coupling of Oxazolidinones with Bromoiodoarenes

We describe the highly selective copper-catalyzed Ullmann-type coupling of bromoiodoarenes with oxazolidinones. 3,4,7,8-Tetramethyl-1,10-phenanthroline (Me4Phen) was identified as an optimal ligand promoting the desired C-N bond formation, while minimizing the competitive bromo-iodo exchange pathway that leads to formation of iodo-substituted and bis-coupled side products. The developed method is highly selective with a >98:2 ratio of the bromo- vs iodo-substituted compounds obtained in the isolated products.

Catalytic asymmetric protonation of chiral calcium enolates via 1,4-addition of malonates

Catalytic asymmetric protonation of chiral calcium enolates was performed. Chiral calcium enolates, prepared in situ from imides and malonates via 1,4-addition in the presence of catalytic amounts of Ca(OEt)2, Ph-PyBox, and achiral phenol, were smoothly protonated to afford adducts bearing tertiary asymmetric carbons in high yields with high enantioselectivities. The adducts were readily converted to optically active 2-substituted 1,5-dicarboxylic acid derivatives.
