A concise asymmetric synthesis of (-)-virolin, (-)-surinamensin,(-)- raphidecursinol B and (-)-polysphorin

Highly concise and general asymmetric syntheses of biologically important natural (-)-8,4-oxyneolignans [(-)-virolin, (-)-surinamensin, (-)-raphidecursinol B, and (-)-polysphorin] are reported. The key step in the synthesis is the Evan’s syn-aldol reaction to achieve the adducts with the desired stereochemistry. The four biologically important plant metabolites were synthesized using two common intermediates. Georg Thieme Verlag Stuttgart · New York.

Structure-Based Evolution of Subtype-Selective Neurotensin Receptor Ligands

Subtype-selective agonists of the neurotensin receptor NTS2 represent a promising option for the treatment of neuropathic pain, as NTS2 is involved in the mediation of mu-opioid-independent anti-nociceptive effects. Based on the crystal structure of the subtype NTS1 and previous structure-activity relationships (SARs) indicating a potential role for the sub-pocket around Tyr11 of NT(8-13) in subtype-specific ligand recognition, we have developed new NTS2-selective ligands. Starting from NT(8-13), we replaced the tyrosine unit by beta2-amino acids (type 1), by heterocyclic tyrosine bioisosteres (type 2) and peptoid analogues (type 3). We were able to evolve an asymmetric synthesis of a 5-substituted azaindolylalanine and its application as a bioisostere of tyrosine capable of enhancing NTS2 selectivity. The S-configured test compound 2a, [(S)-3-(pyrazolo[1,5-a]pyridine-5-yl)-propionyl11]NT(8-13), exhibits substantial NTS2 affinity (4.8 nm) and has a nearly 30-fold NTS2 selectivity over NTS1. The (R)-epimer 2b showed lower NTS2 affinity but more than 600-fold selectivity over NTS1. Tyrosine surrogates: Peptides 2a,b showed that the 5-substituted azaindolylalanine is an appropriate bioisostere of tyrosine capable of enhancing NTS2 selectivity. Compound 2a exhibits single-digit nanomolar affinity (4.8 nm) and a nearly 30-fold NTS2 selectivity over NTS1.

Thermoresponsive Alignment Media in NMR Spectroscopy: Helix Reversal of a Copolyaspartate at Ambient Temperatures

Poly(aspartic acid esters) are known to form either right-or left-handed alpha-helices depending on the ester group in the side chain, on solvent and/or on temperature. Polyphenethyl-l-aspartates (PPLA) exhibit a helix reversal from the right- to the left-handed form with increasing temperature. We have recently reported the application of polyphenethylaspartates as helically chiral alignment media. The thermoresponsivity observed for these polymers offers the possibility to measure different orientations of analytes before and after helix reversal of the alignment medium at 373 K. Herein we present a synthesized copolymer of phenethyl- and benzylaspartate as a new alignment medium undergoing this helix reversal at 303?313 K. Thus, the measurement of residual dipolar couplings (RDC) before and after the helix reversal is allowed for at ambient temperatures. A complete sign change of all 1H?13C RDCs was observed, which is close to the highest possible difference in NMR spectra.

In an article，Which mentioned a new discovery about 108149-65-1

An efficient synthesis of a configurationally stable L-serinal derivative 8 was achieved using an N-hydroxymethyl group in about 50% overall yield in four steps from L-serine. Not more than 1% racemization was observed during the preparation of 8. Its enantiomeric integrity was maintained for at least 15 days at room temperature, and it was stable on silica gel. The orthogonal protective groups of 8 would make it a useful chiral synthon.

A new method for the preparation of Xxx-Gly (E)-alkene dipeptide isosteres (EADIs), using LDA deprotonation followed by 1 N HCl quench, was explored. The method, named kinetic deconjugation, enabled the synthesis of Tyr-Gly, Gly-Gly, Ser-Gly, Pro-Gly, and Phe-Gly EADIs, as well as one Tyr-Gly trisubstituted alkene dipeptide isostere (TADI). Overall, this method, based on commercially available materials, leads to high yields, requires few synthetic steps and works on the gram scale in the synthesis of a wide variety of EADIs.

Modest to high levels of asymmetric induction are observed with Grignard additions to Garner type aldehydes. The resultant secondary alcohols are important precursors of chiral building blocks for asymmetric synthesis and we have demonstrated that they can be readily converted into their respective gamma-hydroxy-beta-amino alcohols and beta-hydroxyamino acids. Additionally, aryloxy ethers, important components of many natural products, can be obtained from these precursors.
