Coote, Susannah C. published the artcileStereoselective aziridination of cyclic allylic alcohols using chloramine-T, Application In Synthesis of 7080-50-4, the publication is Organic & Biomolecular Chemistry (2008), 6(23), 4299-4314, database is CAplus and MEDLINE.

The stereoselective aziridination of a range of cyclic allylic alcs. using two different chloramine salts (4-MeC₆H₄SO₂NClNa, TsNClNa and Me₃CSO₂NClNa, BusNClNa) has been explored. The stereoselectivity of these reactions was highly dependent on the structure of the allylic alc. and the chloramine salt. Generally, mixtures of cis- and trans-hydroxy aziridines were obtained, in which the major diastereomer was the cis-hydroxy aziridine, while complete cis-diastereoselectivity was observed in the aziridination of 1,3-disubstituted allylic alcs. In each case studied, aziridination using BusNClNa gave higher cis-stereoselectivity than that observed for the same reaction using TsNClNa. Unexpectedly, application of the aziridination conditions to 1-substituted cyclopent-2-en-1-ols did not generate the aziridines. Instead, epoxy sulfonamides were obtained.

Head-to-side-chain macrocyclic peptides, and neoglycopeptides, were readily prepared by site-specific amidation of aspartic and glutamic acid side-chain hydrazides. Hydrazides, serving as latent thioesters, were introduced through regioselective opening of the corresponding N_α-Fmoc (Fmoc = 9-fluprenylmethoxycarbonyl) protected anhydride precursors.

Mangion, Ian K. published the artcileIridium-Catalyzed X-H Insertions of Sulfoxonium Ylides, Computed Properties of 5034-06-0, the publication is Organic Letters (2009), 11(16), 3566-3569, database is CAplus and MEDLINE.

The unique reactivity of sulfoxonium ylides as a carbene source is described for a variety of X-H bond insertions, taking advantage of a simple, com. available iridium catalyst. This method has applications in both intra- and intermol. reactivity, including a practical ring-expansion strategy for lactams. The safety and stability of sulfoxonium ylides recommend them as preferable surrogates to traditional diazo ketones and esters.

Sardo, Carla published the artcileWhen Functionalization of PLA Surfaces Meets Thiol-Yne Photochemistry: Case Study with Antibacterial Polyaspartamide Derivatives, Formula: C7H16ClNO2, the publication is Biomacromolecules (2014), 15(11), 4351-4362, database is CAplus and MEDLINE.

In this work we wish to report on the covalent functionalization of polylactide (PLA) surfaces by photoradical thiol-yne to yield antibacterial surfaces. At first, hydrophilic and hydrophobic thiol fluorescent probes are synthesized and used to study and optimize the conditions of ligation on alkyne-PLA surfaces. In a second part, a new antibacterial polyaspartamide copolymer is covalently grafted. The covalent surface modification and the d. of surface functionalization are evaluated by SEC and XPS analyses. No degradation of PLA chains is observed, whereas covalent grafting is confirmed by the presence of S2p and N1s signals. Antiadherence and antibiofilm activities are assessed against four bacterial strains, including Gram-neg. and Gram-pos. bacteria. A strong activity is observed with adherence reduction factors superior to 99.98% and biofilm formation decreased by 80%. Finally, in vitro cytocompatibility tests of the antibacterial surfaces are performed with L929 murine fibroblasts and show cell viability without promoting proliferation.

Hanaoka, Shigeyuki published the artcileDetermination of mustard and lewisite related compounds in abandoned chemical weapons (Yellow Shells) from sources in China and Japan, Application In Synthesis of 1002-41-1, the publication is Journal of Chromatography A (2006), 1101(1-2), 268-277, database is CAplus and MEDLINE.

Knowledge of the states of the contents in chem. munitions that Japanese Imperial Forces abandoned at the end of World War II in Japan and China is gravely lacking. To unearth and recover these chem. weapons and detoxify the contents safely, it is essential to establish anal. procedures to definitely determine the CWA contents. We established such a procedure and applied it to the anal. of chems. in the abandoned shells. Yellow shells are known to contain sulfur mustard, lewisite, or a mixture of both. Lewisite was analyzed without thiol derivatization, because it and its decomposition products yield the same substances in the derivatization. Anal. using our new procedure showed that both mustard and lewisite remained as the major components after the long abandonment of ∼60 yr. The content of mustard was 43% and that of lewisite 55%. The viscous material found was suggested to be mostly oligomers of mustard. Comparison of the components in the Yellow agents with mustard recovered in both Japan and China showed a difference in the impurities between the CWAs produced by the former Imperial navy and those by the former Imperial army.

Gorst-Allman, Charles P. published the artcileSynthetic approaches to the austocystins, mycotoxins from Aspergillus ustus. Part I, Name: 3-Chloro-2,6-dimethoxybenzoic acid, the publication is South African Journal of Chemistry (1978), 31(4), 143-8, database is CAplus.

Two approaches to the synthesis of ustocystin A (I) were investigated. 2,6-(MeO)₂C₆H₃CO₂H was converted into the 3-Cl derivative (II) by chlorination with SO₂Cl₂. The acid chloride of II was treated with 2,4,6-(MeO)₃C₆H₂Li to give III (R = Me), which was selectively demethylated to give III (R = H; IV). Alk. condensation of IV gave 2 xanthoses V [R = H, R¹ = Cl; R = Cl, R¹ = H (VI)] in a 12:1 ratio. VI was the desired xanthone for I preparation The focal point of the second approach was the use of a 4-methylcoumarin as a masked dehydrofurobenzofuran. VII was necessary for this approach but its isomer VIII (R = Me) was obtained. The x-ray structure of VIII (R = H) was determined
