Simple and efficient routes to substituted oxazolidine and spiro-oxindole systems by one-pot synthetic strategies

Simple and efficient strategies towards the synthesis of substituted spiro-oxindole and oxazolidine systems by one-pot multi-component catalyst-free reactions utilising aryl aldehydes and alpha-amino acids have been developed. Owing to their complicated structure and ring strain spiro-oxindole moieties are not easily synthesised. In either route 1,3-dipolar cycloadditions involving non-stabilised azomethine ylides as intermediates, generated in situ from amino acids and aldehydes, with the dipolarophile present in the reaction mixture viz. (E)-beta-nitrostyrene, were utilised. The route to substituted oxazolidines involved cycloaddition to the C=O bond of a second molecule of the aldehyde.

A Zero Cross-Talk Ratiometric Two-Photon Probe for Imaging of Acid pH in Living Cells and Tissues and Early Detection of Tumor in Mouse Model

Acid-base disorders disrupt proper cellular functions, which are associated with diverse diseases. Development of highly sensitive pH probes being capable of detecting and monitoring the minor changes of pH environment in living systems is of considerable interest to diagnose disease as well as investigate biochemical processes in vivo. We report herein two novel high-resolution ratiometric two-photon (TP) fluorescent probes, namely, PSIOH and PSIBOH derived from carbazole-oxazolidine pi-conjugated system for effective sensing and monitoring acid pH in a biological system. Remarkably, PSIOH exhibited the largest emission shift of similar to 169 nm from 435 to 604 nm upon pH changing from basic to acidic with an ideal pK(a) value of 6.6 within a linear pH variation range of 6.2-7.0, which is highly desirable for high-resolution tracking and imaging the minor fluctuation of pH in live cells and tissues. PSIOH also exhibits high pH sensitivity, excellent photostability, and reversibility as well as low cytotoxicity. More importantly, this probe was successfully applied to (i) sense and visualize the pH alteration in HeLa cells caused by various types of exogenous stimulation and (ii) detect and differentiate cancer and tumors in liver tissues and a mouse model, realizing its practical in vitro and in vivo applications.

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.

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.

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.
