In the present study, a new synthetic strategy towardsN-acylated glycinamides was developed by the use of 1,3,5-triazinanes as formaldimine surrogates in the Ugi reaction. The targeted products were obtained in a combinatorial, diversity-oriented fashion in good yields. Further modifications allowed us to adapt this procedure for the one-pot two-step syntheses of a local anesthetic druglidocaine and several unsymmetrically substituted diketopiperazines.

Fluorescent silicon nanoparticles (SiNPs) displayed different emission wavelengths have been synthesized, but it has not been reported that the preparation of wavelength controllable SiNPs by adjusting the nitrogen content of reducing agents. In this paper, the wavelength-controlled fluorescent SiNPs were prepared by selecting the dopamine (DA) with nitrogen content between catechol and 2-aminophenol as the reducing agent and N-[3-(trimethoxysilyl) propyl]-ethylenediamine (DAMO) as the silicon source via one-step hydrothermal method. The emission wavelength of the prepared SiNPs was in direct proportion to the nitrogen content in the reducing agent. To the best of our knowledge, this is the first time for exploring the nitrogen content in reducing agents could affect the optical properties of SiNPs so far. In addition, the obtained SiNPs could be applied to determinate 2-nitrophenol (2-NP). Based on the combination action of inner filter effect (IFE) and static quenching effect (SQE) mechanism, a wide linear range was obtained from 0.1 to 500 mu M, and the limit of detection was 0.029 mu M for 2-NP, which was comparable to or even lower than some previous reports. This SiNPs probe was also successfully employed for sensing of 2-NP in industrial effluent with satisfactory results (98.6%-103.4%).

We describe the synthesis of 10-aza-9-oxakalkitoxin, an N,N,O-trisubstituted hydroxylamine-based analog, or hydroxalog, of the cytotoxic marine natural product kalkitoxin in which the -NMe-O- moiety replaces a -CHMe-CH2- unit in the backbone of the natural product. 10-Aza-9-oxakalkitoxin displays potent and selective cytotoxicity (IC50 2.4 ng mL(-1)) comparable to that of kalkitoxin itself (IC50 3.2 ng mL(-1)) against the human hepato-carcinoma cell line HepG2 over both the human leukemia cell line CEM and the normal hematopoietic CFU-GM. Like kalkitoxin, and contrary to the common expectation for hydroxylamines, 10-aza-9-oxakalkitoxin is not mutagenic.

A simple and general approach towards the total syntheses of several iridolactones such as (+/-)-boschnialactone, (+/-)-7-epi-boschnialactone, (+/-)-teucriumlactone, (+/-)-iridomyrmecin, (+/-)-isoboonein, (+/-)-7-epi-argyol, (+/-)-scabrol A, (+/-)-7-epi-scabrol A, and (+/-)-patriscabrol as well as the putative structure of scholarein A is delineated. The synthetic strategy features a diastereoselective intramolecular Pauson-Khand reaction (IPKR) to construct the iridoid framework followed by some strategic synthetic manipulations to access the targeted monoterpenes including those having diverse oxy-functionalization patterns and with 3-5 contiguous stereogenic centres in a highly stereocontrolled manner. Also, the present endeavour includes the first total synthesis of scabrol A.

A survey of existing stationary phases classified by the United States Pharmacopeia reveals that 120 groups of chromatographic supports mostly utilize silica-silane chemistry, polymeric materials along with some niche metal oxides. In this work, the synthesis and characterization of transition-metal free geopolymers as a new class of stationary phases for hydrophilic interaction liquid chromatography and normal phase separations is reported. The geopolymers were synthesized by reaction of synthetic aluminosilicate with potassium silicate (fumed silica dissolved in KOH) in a water-in-oil emulsion. For comparative purposes of peak shapes, a geopolymer from natural metakaolin was also synthesized. The geopolymers were examined by X-ray diffraction, energy dispersive spectroscopy, laser diffraction, and N-2-adsorption isotherms. This two-step approach gives spherical microparticles with surface area and pore size comparable to silica phases (150 m(2)/g and 120 angstrom respectively). Both synthetic aluminosilicates based and natural metakaolin based geopolymers occupy a unique spot in the HILIC selectivity chart when compared to 35 HILIC phases. An additional promising feature of geopolymers is high pH and temperature stability which are used to tune selectivity for small polar analytes. High pH separations are shown with carboxylic acids. Geopolymers also show mixed mode behavior in retention with ion-exchange properties in purely aqueous mobile phases. The separation of derivatized sugars is demonstrated and compared with porous graphitic carbon (Hypercarb (TM)) as another pH-stable stationary phase. (C) 2019 Elsevier B.V. All rights reserved.

Chemo selective reduction of a wide range of aromatic nitro compound has been performed by using inexpensive Zn powder and CuSO4 system in water medium at room temperature. This system has high tolerance to other highly reducible groups present in nitro substance along with high conversation and selectivity. This chemo-selective reduction also provides a facile root for the synthesis of other industrially important fine chemicals or biologically important compounds where other highly reducible groups are present in close proximity to the targeted nitro groups.

An article The timing of lunar solidification and mantle overturn recorded in ferroan anorthosite 62237 WOS:000525394900018 published article about SM-ND AGE; MG-SUITE; YOUNG; CONSTRAINTS; ORIGIN; CRUST; MOON; GEOCHEMISTRY; SYSTEMATICS; CHRONOLOGY in [Sio, C.

Ferroan anorthosite suite (FAS) rocks are widely interpreted to represent primordial lunar crust. Despite their importance in pinpointing the timing of lunar crust formation, robust chronological investigations for this rock type are scarce. Here, we report the Ar-Ar, Rb-Sr, and Sm-Nd isotopic systematics for the FAS troctolitic anorthosite 62237. The Ar-Ar isotopic system has been reset by a thermal event at 3710 +/- 48 Ma, and the Rb-Sr isotopic systematics has been disturbed such that a Rb-Sr isochron age cannot be determined. However, an internal isochron for the Sm-Nd isotopic system has yielded an age of 4350 +/- 73 Ma (MSWD = 2.0) with an initial epsilon Nd-143(CHUR) of -0.53 +/- 0.26. The mineral and whole-rock fractions of 62237 plot on the same internal isochron as FAS sample 60025. The combined datasets define an age of 4372 +/- 35 Ma (MSWD = 4.0) with an initial epsilon Nd-143(CHUR) of -0.17 +/- 0.22. Literature Sm-Nd data for FAS and Mg-suite whole-rocks also plot on the 60025-62237 isochron. The coherence of data from both FAS and Mg-suite rocks examined thus far suggests that both rock suites formed contemporaneously from identical, or nearly identical, sources. In addition, the concordance of FAS and Mg-suite ages suggests that primordial crust solidification either involved both magmatic suites, or that Mg-suite magmatism was contemporaneous with FAS magmatism within resolution of the Sm-Nd chronometer. The ages for FAS and Mg-suite also coincide with the formation ages of the mare basalt source regions and urKREEP. Ferroan anorthosite suite rocks and urKREEP are thought to represent primordial LMO solidification products, whereas Mg-suite and the mare basalt source regions are argued to represent mixtures of various LMO crystallization products that were formed during density-driven overturn of the LMO. The concordance of ages implies that the 4372 +/- 35 Ma Sm-Nd isochron records the age of mantle overturn, and that overturn occurred during, or shortly after, solidification of the LMO.
