Microstructure and irradiation hardening of V-4Cr-4Ti alloys with different yttrium (Y) contents were studied by self-ion at 550 °C via TEM nano-indentation test technology. The peak damage the V-4Cr-4Ti-xY alloy (x = 0, 0.1, 0.5, 1, wt.%) irradiated 2.5 MeV (V2+) is 8 dpa. Dense dislocation loops observed in all vanadium samples after irradiation. With increase Y content, both average size num...

Correction for ‘Amenamevir by Ugi-4CR’ Xin Li et al. , Green Chem. 2023, 25 1322–1325, https://doi.org/10.1039/D2GC04869H.

By combining an Ugi-4CR and a gold-catalyzed cascade cyclization, diverse benzazepinoindoles are assembled in step-economical, chemo- regioselectivity fashion.

A metal-free chemodifferentiating A2BB' 4CR manifold for the modular synthesis of tertiary skipped diynes is described. The manifold performs a triethylamine triggered reaction of alkyl propiolates and acid chlorides to assemble two units of each component in the form of two propargylic alkynoates, a tertiary alcohol, and an ester. A differentiated incorporation of the two acid chloride compone...

A library of ten 1,3-diyne-linked peptoids has been synthesized through an Ugi four-component reaction (U-4CR) followed by a copper-catalysed alkyne homocoupling (Glaser reaction). The short and chemoselective reaction sequence allows generating diverse (pseudo) dimeric peptoids. A combinatorial version allows the one-pot preparation of, e.g., six-compound-libraries of homo- and heterodimers ve...

A practical, integrated and versatile U-4CR-based assembly of 1,4-benzodiazepin-2-ones exhibiting functionally, skeletally, and stereochemically diverse substitution patterns is described. By virtue of its convergence, atom economy, and bond-forming efficiency, the methodology documented herein exemplifies the reconciliation of structural complexity and experimental simplicity in the context of...

A novel selectively sequential C-S/C-N bond activation is presented. Through the combination of an Ugi-4CR and cleavage, diverse peptidomimetics containing a primary amide are prepared in a...

The effect of post-irradiation annealing on the microstructures and mechanical properties of V-4Cr-4Ti alloys was studied. Helium-hydrogen-irradiated sequentially V-4Cr-4Ti alloys at room temperature (RT) were undergone post-irradiation annealing at 450 °C over periods of up to 30 h. These samples were carried out by high-resolution transmission electron microscopy (HRTEM) observation and nanoi...

Passerini (P-3CR) and Ugi (U-4CR) reactions were investigated in 4-oxoazetidine-2-carboxaldehydes, affording the corresponding Passerini and Ugi adducts with moderate diastereoselectivity in high yields. Fortunately, the obtained mixtures of isomers syn/anti were separated in most cases. The scope of both IMCRs has been studied using a variety of isocyanides, carboxylic acids and amines. Ugi ad...

Thermally sprayed cermet coatings are adequate solutions to improve cavitation and wear resistance of hydraulic turbines made stainless steel (SS), especially in rivers with a high sediment load, such as the Madeira River Brazil. However, some cermets easily dissolved river water, leading premature failure coating costly maintenance. Moreover, galvanic corrosion induced by coupling SS can accel...
