Highly stereoselective N-terminal functionalization of small peptides by chiral phase-transfer catalysis

Virtually complete chirality transfer has been realized in the N-terminal alkylation of small, Schiff-base activated peptides under mild phase-transfer conditions, in which finely tuned chiral quaternary ammonium salts are used as catalysts. Repeated extension and alkylation of the N-terminal position can lead selectively to nonnatural oligopeptides (see picture).

Solid-state Suzuki-Miyaura cross-coupling reactions: Olefin-accelerated C-C coupling using mechanochemistry

The Suzuki-Miyaura cross-coupling reaction is one of the most reliable methods for the construction of carbon-carbon bonds in solution. However, examples for the corresponding solid-state cross-coupling reactions remain scarce. Herein, we report the first broadly applicable mechanochemical protocol for a solid-state palladium-catalyzed organoboron cross-coupling reaction using an olefin additive. Compared to previous studies, the newly developed protocol shows a substantially broadened substrate scope. Our mechanistic data suggest that olefin additives might act as dispersants for the palladium-based catalyst to suppress higher aggregation of the nanoparticles, and also as stabilizer for the active monomeric Pd(0) species, thus facilitating these challenging solid-state C-C bond forming cross-coupling reactions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4923-87-9 is helpful to your research. Electric Literature of 4923-87-9

An improved synthesis of benzo[b]thiophene and its derivatives using modified montmorillonite clay catalysts

Methods for the preparation of benzothiophene (3) and its derivatives by cyclization of phenylthioacetals (1) over ZnCl2-promoted montmorillonite clay are described. Reactions in solution resulted in only moderate (ca. 50%) yields of 3 and the formation of diphenyl disulfide (4) and uncharacterized products. The production of 4 was explained by coordination of 1 via its oxygen atom to active sites of the catalyst and subsequent bimolecular processes. Good to excellent yields (67-98%) of 3 and its derivatives were obtained using vapor phase techniques at 200-300C to promote the desired intramolecular cyclizations.

A luminescent steroid-based organogel: ON-OFF photoswitching by dopant interplay and templated synthesis of fluorescent nanoparticles

The modulation of the fluorescence emission of a perylene dye between ON and OFF states was achieved with high efficiency by means of a diarylethene photochromic compound in an organogel medium. Fluorescent gels were prepared from a steroidal low molecular weight organogelator doped with the perylene fluorophore. The compatibility of the photochromic compound in this medium and the non-destructive readout capability were demonstrated. The dye doped organogel was further used as a template and an innovative method was employed to grow fluorescent silica spherical nanoparticles with physically and chemically admixed perylene dye.

Phosphine-catalyzed dearomative (3 + 2) annulation of 2-nitrobenzofurans and nitrobenzothiophenes with allenoates

An efficient Ph2PMe-catalyzed dearomative (3 + 2) annulation of 2-nitrobenzofurans, 2-nitrobenzothiophenes, and 3-nitrobenzothiophenes with allenoates has been developed. With the developed protocol, a series of structurally important cyclopenta[b]benzofurans and cyclopenta[b]benzothiophenes were obtained in good to excellent yields (up to 98%) under mild conditions. In addition, preparative-scale experiments and transformations were conducted to exemplify the synthetic utility. The asymmetric version of this dearomative (3 + 2) annulation reaction was tentatively investigated by using chiral phosphine catalysts.

A Chimeric SERM-histone deacetylase inhibitor approach to breast cancer therapy

Breast cancer remains a significant cause of death in women, and few therapeutic options exist for estrogen receptor negative (ER (-)) cancers. Epigenetic reactivation of target genes using histone deacetylase (HDAC) inhibitors has been proposed in ER (-) cancers to resensitize to therapy using selective estrogen receptor modulators (SERMs) that are effective in ER (+) cancer treatment. Based upon preliminary studies in ER (+) and ER (-) breast cancer cells treated with combinations of HDAC inhibitors and SERMs, hybrid drugs, termed SERMostats, were designed with computational guidance. Assay for inhibition of four typea I HDAC isoforms and antagonism of estrogenic activity in two cell lines yielded a SERMostat with 1-3a muM potency across all targets. The superior hybrid caused significant cell death in ER (-) human breast cancer cells and elicited cell death at the same concentration as the parent SERM in combination treatment and at an earlier time point.
