Novel Z -stereoretentive metathesis catalysts with enhanced stability and outstanding stereoselectivity are reported. They demonstrate a broad substrate scope diverse applications, offering new possibilities for advanced synthetic transformations.
A route towards pyrrolo[2,1-<italic>a</italic>]isoquinolines through a 3CR of 1-aroyl dihydroisoquinolines, activated alkynes and alcohols has been developed.
A number of aza-heterocyclic compounds, which share the 5,6-dihydropyrrolo[2,1-a]isoquinoline (DHPIQ) scaffold with members lamellarin alkaloid family, were synthesized and evaluated for their ability to reverse in vitro multidrug resistance cancer cells through inhibition P-glycoprotein (P-gp) and/or multidrug-resistance-associated protein 1. Most investigated DHPIQ compounds proved be selective P-gp modulators, most potent modulator,...
An efficient synthesis of pyrrolo[2,1-a]isoquinolines by a domino reaction from variety 3,4-dihydropyrrolo[2,1-a]isoquinolines and α,β-unsaturated aldehydes in the absence catalyst good yields under microwave irradiation, is reported.
We herein demonstrate a new approach for the synthesis of 2,4‐disubstituted pyrroles by [3+2] cycloaddition reaction isocyanides to activated double bond various enamines and enaminones. This process paved way series pyrroles, which are known be intermediates in biologically active compounds, good excellent yields from simple commercially available starting materials. The is carried out efficiently using strong base, t BuOK, at low temperatures (0 °C). described method simple, proceeds one...
Abstract A range of novel BODIPYs with the isoxazolyl groups at 1,7‐positions were prepared from 3‐(4‐chlorophenyl)‐5‐(5‐phenyl‐1H‐pyrrol‐3‐yl)isoxazole and their photophysical properties characterized. The presence 1,7‐positions, shifts long‐wavelength absorption 581±4 nm emission 622±3 in near‐infrared region. comparison three variants substituents positions 1,7 BODIPY core is shown.
Abstract Pyrroles are an interesting class of heterocyclic compounds due to their widespread use both in medical chemistry and the new materials. Search development effective methods for synthesis pyrrole ring is urgent task. Along with this, systematization already known equally important Herein, we focused on results NH‐pyrroles that have been obtained since 2015.
A first clathrate compound with selenium guest atoms, [Ge46–xPx]Se8–y□y (x = 15.4(1); y 0–2.65; □ denotes a vacancy), was synthesized as single-phase and structurally characterized. It crystallizes in the space group Fm3̅ unit cell parameter varying from 20.310(2) to 20.406(2) Å corresponding 2 × supercell of usual clathrate-I structure. The superstructure is formed due symmetrical arrangement three-bonded framework atoms appearing result transformation parent Selenium occupy two types...
One of the main drawbacks stereoretentive ruthenium catalysts that allow synthesis olefins with defined double bond geometry is their limited stability in presence oxygen. To remove bottleneck inhibits its widespread use, we prepared a series Hoveyda-Grubbs-type complexes modified ether moiety benzylidene substituent. Although yields obtained air are still lower than reactions carried out an inert gas atmosphere, Ru21 complex typically led to better high selectivities compared benchmark...
Using 3-phenyl-5-(5-phenyl-1 H -pyrrol-3-yl)-1,2,4-oxadiazole, BODIPYs with the oxadiazole groups at 1,7-positions were prepared and their photophysical properties characterized.
Rationale Direct non‐derivatization analysis of organic acids and acidic compounds by matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry (MS) in positive ion mode is not always possible due to the low ionization efficiency analytes. Some new efficient deprotonating matrices were suggested that allowed production negative ions from during MALDI‐MS experiments. Methods Various tested carboxyl‐containing as well with properties mixed [4‐dimethylaminobenzaldehyde (DMABA), N,N...
The introduction of electron donating groups or withdrawing into the phenyl ring at meso position 1,7-aroyl BODIPY significantly influences fluorescence quantum yield.
