Preparation of Enantiomerically Pure beta,beta-Diaryl beta-Hydroxy-alpha-Amino Acids and Evaluation of Their Potential as Organocatalysts

A general synthetic procedure was developed for enantiomerically pure beta,beta-diaryl beta-hydroxy-alpha-amino acids 5, starting from readily available oxazolidine ester 1 and a wide variety of Grignard reagents. The problematic oxidative decomposition of beta-aminodiols 3, due to their instability in the presence of metallic oxidants, was successfully suppressed using Parikh-Doering oxidation and subsequent Pinnick oxidation. Additionally, the organocatalytic ability of beta,beta-diaryl beta-hydroxy-alpha-amino acids 5 was evaluated with respect to asymmetric fluorination of 2-phenylpropionaldehyde 6, and moderate enantioselectivity, 61%, was achieved using compound 5 f.

Diastereoselective intramolecular aldol ring closures of threonine derivatives leading to densely functionalised pyroglutamates related to oxazolomycin

Intramolecular aldol reactions on oxazolidine templates derived from threonine may be used to generate libraries of densely functionalised pyroglutamates with a high level of diastereoselectivity; the oxazolidine precursors themselves are suitable for further direct manipulation by side chain alkylation, permitting rapid access to cyclised products with several points of chemical diversity. Although these systems may be considered to be structural mimics of the functionalised pyroglutamate portion of oxazolomycin, little antibacterial activity against S. aureus and E. coli was found. These systems may additionally have application as three-dimensional fragments for drug discovery and development.

SERINOL DERIVATIVES FOR THE SUSTAINABLE VULCANIZATION OF DIENE ELASTOMERS

2-amino-1,3-propandiol (serinol) was used as the starting building block of synthetic pathways that led to the preparation of innovative chemicals suitable as ingredients for rubber compounds. Serinol based reactions were performed in the frame of a sustainable process, in the absence of any solvent and catalyst, with aldehydes and ketones, such as acetone, cinnamaldehyde and camphor. The synthesis of either imines or oxazolidines was obtained with high selectivity. Serinol, imine and oxazolidine derivatives of serinol were used as accelerator for the vulcanization of diene rubbers. They were proved to be efficient secondary accelerators in silica based compounds based on poly(styrene-co-butadiene) in place of diphenyl guanidine. The kinetics of vulcanization was investigated for natural rubber based compounds in the absence of any filler. With respect to serinol, the imine derivatives were able to enhance the induction time of vulcanization and to afford a similar vulcanization rate.

2D-Coordination polymer containing lead(II) in a hemidirected PbO4S3 environment formed by molecular breaking of the 1,3-oxathiolane ligand

A new 1,3-oxathiolane-based ligand, 2-(1,3-oxathiolan-2-yl)pyridine, was prepared and its coordination to lead(II) was investigated. Experiments revealed a ligand-breaking reaction during the complexation process, which leads to the formation of a 2D-coordination polymer of lead(II), [Pb(mu(3)-HME)(mu-OAc)](n); H2ME: 2-mercaptoethanol. The compounds have been characterized by elemental analysis, FT-IR, H-1 NMR spectroscopy and single-crystal X-ray diffraction. X-ray analysis revealed a 2D-coordination polymer extending via acetato bridges. The lead(II) center adopts a rare PbO4S3-distorted pentagonal bipyramidal geometry with a hemidirected arrangement. Upon coordination, the thiol group of the H2ME ligand is deprotonated to coordinate as an anionic ligand. The network extends in sheets in the crystallographic ab plane via Pb-S-Pb and Pb-O-Pb bridges, aided by O-H center dot center dot center dot O hydrogen bonds.

Batch- and Continuous-Flow Aerobic Oxidation of 14-Hydroxy Opioids to 1,3-OxazolidinesA Concise Synthesis of Noroxymorphone

14-Hydroxymorphinone is converted to noroxymorphone, the immediate precursor of important opioid antagonists, such as naltrexone and naloxone, in a three-step reaction sequence. The initial oxidation of the N-methyl group in 14-hydroxymorphinone with in situ generated colloidal palladium(0) as the catalyst and molecular oxygen as the terminal oxidant constitutes the key transformation in this new route. This oxidation results in the formation of an unexpected oxazolidine ring structure. Subsequent hydrolysis of the oxazolidine under reduced pressure followed by hydrogenation in a packed-bed flow reactor using palladium(0) as the catalyst provides noroxymorphone in high purity and good overall yield. To overcome challenges associated with gas-liquid reactions with molecular oxygen, the key oxidation reaction was translated to a continuous-flow process.

A general strategy to increase emission shift of two-photon ratiometric pH probes using a reversible intramolecular reaction of spiro-oxazolidine

Fluorescent pH probes have been served as powerful tools in biological and pathological studies in recent years due to the important roles of pH values in various physiological processes. Although plenty of pH probes have been delivered, development of two-photon ratiometric pH probes with large emission shift for detecting the variation of intracellular pH values is still a greatly challenging task. To address this concern, in this work, we have discovered a general strategy designing pH probes by means of a pH-dependent reversible intramolecular reaction of spiro-oxazolidine which can efficiently change their conjugation length and the electronic effect con-currently. To display the generality of the strategy, we have synthesized six pH probes, and all these probes exhibit short emission in basic conditions and dramatically red-shifted emission in acid environments. The emission shift of the six probes is more than 150 nm and even up to 210 nm, much larger than shift of all commercial and reported pH probes. The chemical sensing mechanism of intramolecular ring opening/closing reaction of spiro-oxazolidine has been confirmed with H-1 NMR spectra and density functional theory (DFT) calculations. Finally, we have used one of six with oneand two-photon properties to successfully image lysosomal pH changes under confocal and two-photon microscopes in a ratiometric manner. We believed that this spiro-oxazolidine strategy can serve as a general and powerful platform for the design of ideal pH probes. (C) 2020 Elsevier B.V. All rights reserved.
