Gerstenberger, Ina published the artcileRegioselective and stereoselective transformations of enantiopure para-benzoquinone equivalents, Synthetic Route of 5034-06-0, the publication is European Journal of Organic Chemistry (1998), 643-650, database is CAplus.

The selectivities of typical transformations of the 1,4-benzoquinone Diels-Alder adduct I (RR¹ = bond) and its dihydro derivative I (R, R¹ = H) are highly dependent on the mechanistic path followed. To avoid ambiguities and to make sure of clearly defined regioselectivity, 1,4-benzoquinone monoethylene ketal was examined and proven not only to be an excellent dienophile but, of course, also to lead to reliable regioselectivity in subsequent transformations. This led to the correction of an earlier provisional assignment of alkylation products.

Chlorosulfates ClSO₃R (R = CH₂Cl, Me, CHMeCl, Bu, Et) and (ClSO₃)₂CH₂ were used to esterify several carboxylic acids, i.e., penicillanic acid derivatives, BzOH, and alkanoic acids. Thus, penicillanic acid sulfone was converted to the chloromethyl ester by treatment with ClSO₃CH₂Cl in H₂O-CH₂Cl₂ in the presence of NaHCO₃ and Bu₄N⁺HSO₄^–.

Brueckner, Alexander C. published the artcileVisible-light-mediated, nitrogen-centered radical amination of tertiary alkyl halides under metal-free conditions to form α-tertiary amines, Application of 2-Chlorotrityl chloride, the publication is Organic & Biomolecular Chemistry (2016), 14(19), 4387-4392, database is CAplus and MEDLINE.

A mild and operationally convenient amino-functionalization of a range of tertiary alkyl halides by reaction with iminoiodinanes (PhI=NNs) and I₂ was developed. According to the mechanistic experiments described within the reaction was speculated to proceed through a light-promoted, N-centered radical pathway involving a N,N-diiodosulfonamide reactive species. This method of direct N-incorporation offers an attractive alternative to the production of α-tertiary amines, a synthetically challenging structural class found in a variety of bioactive mols.

Li, Ziyong published the artcileConstruction of photoswitchable rotaxanes and catenanes containing dithienylethene fragments, Related Products of chlorides-buliding-blocks, the publication is Organic & Biomolecular Chemistry (2015), 13(26), 7313-7322, database is CAplus and MEDLINE.

Mech. interlocked structures such as rotaxanes and catenanes provide a novel backbone for constructing functional materials with unique structural characteristics. In this study, we have designed and synthesized a series of photoswitchable rotaxanes and catenanes containing photochromic dithienylethene fragments using a template-directed clipping approach based on dynamic imine chem. Their structures have been confirmed using NMR, mass spectrometry and elemental anal. Investigations into their photoisomerization properties indicated that these dithienylethene-based mech. interlocked mols. have good reversibility and excellent fatigue resistance upon irradiation with UV or visible light. Interestingly, the mech. interlocked mols. containing two dithienylethene backbones display around a 2-fold increase in the molar absorption coefficient compared with that of the mono dithienylethene derivative Furthermore, the introduction of the fluorophore pyrene in the dithienylethene component facilitates these mols. to serve as fluorescent switches.

Kang, Seung-Hyun published the artcilePhosphonium Chloride-Catalyzed Dehydrochlorinative Coupling Reactions of Alkyl Halides with Hydridochlorosilanes, Name: Dichloro(hexyl)(methyl)silane, the publication is Organometallics (2003), 22(3), 529-534, database is CAplus.

The dehydrochlorinative Si-C coupling reactions of various primary and secondary alkyl chlorides with hydridochlorosilanes in the presence of tetrabutylphosphonium chloride as catalyst gave the coupling products with elimination of HCl as a gas. For example, RCl (R = CH₂C₆H₄X-p; X = H, Cl, F, Me, MeO), when coupled with HSiCl₃ in the presence of catalytic amounts of phosphonium salts [Bu₄Y]Z (Y = P, N; Z = Cl, Br, I) gave RSiCl₃ (R = same as above) in 80-96% yields. Coupling reactions of activated alkyl chlorides such as benzyl chlorides proceeded at 130°, while unactivated organic chlorides such as silylalkyl chlorides and secondary alkyl chlorides required higher reaction temperatures of 150 or 170° and longer reaction times. Primary alkyl chlorides reacted with trichlorosilane (1) to give coupling products in good to excellent yields, but secondary alkyl chlorides reacted at a slower rate and gave lower yields of products. Coupling reactions with methyldichlorosilane instead of 1 proceeded at slower rates and gave lower yields of products.

Chen, Jing-Xing published the artcileSynthesis and Chiroptical Properties of Double-Helical (M)- and (P)-o-Oligophenylenes, Safety of ((1S,4R)-7,7-Dimethyl-2-oxobicyclo[2.2.1]heptan-1-yl)methanesulfonyl chloride, the publication is Organic Letters (2015), 17(17), 4296-4299, database is CAplus and MEDLINE.

All of the M and P isomers of optically pure oligophenylenes with 6, 8, 10, and 12 Ph rings were synthesized and fully characterized. The Suzuki cross-coupling reaction has been revealed to be a viable strategy in the syntheses of tetraphenylene derivatives, which, together with the copper-mediated oxidative cross-coupling reaction, were employed in the quest for the oligophenylenes [e.g., (S,S)-I + (M)-II â†?(M)-III (5%) + (M)-IV (6%) + (M)-V (9%) using t-BuLi/CuCl₂]. X-ray diffraction anal. in combination with sp. rotation and CD spectroscopy unambiguously identified the unique covalent double-helical frameworks of these oligophenylene mols.

Hydroxytetraphenylenes with rigid conformations are potential candidates for employment as chiral ligands in asym. synthesis. Highly diastereo- and enantioselective Darzens reactions between aldehydes and diazo-N,N-dimethylacetamide are catalyzed by a chiral titanium complex formed in situ from Ti(OⁱPr)₄ and chiral 1,16-dihydroxytetraphenylene, giving cis-glycidic amides in moderate to high yields with excellent enantiomeric purities (40-99% yield, up to 99% ee).

Chai, Xianzhi published the artcileTargeted photoswitchable imaging of intracellular glutathione by a photochromic glycosheet sensor, Related Products of chlorides-buliding-blocks, the publication is Beilstein Journal of Organic Chemistry (2019), 2380-2389, database is CAplus and MEDLINE.

The development of photochromic fluorescence sensors with dynamic and multiple-signaling is beneficial to the improvement of biosensing/imaging precision. However, elaborate designs with complicated mol. structures are always required to integrate these functions into one mol. By taking advantages of both redox-active/high loading features of two-dimensional (2D) manganese dioxide (MnO₂) and dynamic fluorescence photoswitching of photochromic sensors, we here design a hybrid photochromic MnO₂ glycosheet (Glyco-DTE@MnO₂) to achieve the photoswitchable imaging of intracellular glutathione (GSH). The photochromic glycosheet manifests significantly turn-on fluorescence and dynamic ON/OFF fluorescence signals in response to GSH, which makes it favorable for intracellular GSH double-check in targeted human hepatoma cell line (HepG2) through the recognition between β-D-galactoside and asialoglycoprotein receptor (ASGPr) on cell membranes. The dynamic fluorescence signals and excellent selectivity for detection and imaging of GSH ensure the precise determination of cell states, promoting its potential applications in future disease diagnosis and therapy.
