Optically pure homoallylic alcohols are important synthons for natural products and bioactive compounds, which can be assembled by the chiral phosphoric acid-catalyzed asymmetric allylboration of aldehydes. Based on this reaction, two unprecedented cascade reactions functionalized aldehydes (allylation/oxa-Michael or oxa-Pictet−Spengler reactions) synthesis 2,5-disubstituted 2,2,5-trisubstituted tetrahydrofurans using a single acid catalyst have been developed. The reaction mechanism was...
Electrochromic (EC) fabrics based on conductive polyaniline (PANI) have demonstrated important application potentials in the field of active camouflage due to their ability reversible color switching between yellow and...
Here we report a highly diastereoselective cyano group transfer radical cyclization reaction to construct 5/6-fused bicyclic ring systems that bear three contiguous and congested stereogenic elements, with 100% atom economy under catalyst-free near-ultraviolet light irradiation conditions. Mechanistic investigations density functional theory calculations suggest the diastereoselectivity is governed by conformational distribution of triplet diradical intermediate rate reverse intersystem...
The enantioselective 1,3-dipolar cycloaddition of alkynes and α-aliphatic nitrones has long been recognized as an important challenge, while considerable progress made for the alkenes aromatic nitrones. We herein report example earth-abundant iron-catalyzed click-approach nonterminal alkynyl imides nitrones, highly functionalized chiral 4-isoxazolines having a 3-alkyl-substituted stereogenic carbon center are modularly generated in up to >99% yield 98% ee (54 examples). Although steric bulk...
Abstract Exact analytical solutions are good candidates for studying and explaining the dynamics of solitons in nonlinear systems. We further extend region existence spin nonlinearity coefficient space spin-1 Bose–Einstein condensate. Six types soliton can be obtained, they exist different regions. Stability analysis numerical simulation results indicate that three stable against weak noise. The non-integrable properties model induce shape oscillation increase speed after collision between...
The trivalent phosphine-catalyzed [4+1] spiro-annulation reaction of allenyl imide and activated methylene cyclocompounds has been developed for the construction various spiro-2-cyclopenten-1-ones. Oxindoles, 3-isochromanones, 2-indanones are selected as 1C synthons to capture in situ-generated bis-electrophilic α,β-unsaturated ketenyl phosphonium intermediate, affording corresponding monospiro- bispiro-cyclopentenones good excellent yields (≤91%) under mild conditions. primary attempt at...

With the aim of developing novel annulations via ketene intermediates, allenyl imide and alkynoates bearing good leaving groups are used for their function in a tandem conjugate addition–elimination reaction (SN2′ type) promoted by nucleophilic phosphine catalysts. By utilizing thioamides as 1S,3N-bis-nucleophiles, [3+3] [3+2] have been established to allow rapid access 1,3-thiazin-4-ones 5-alkenyl thiazolones high yields, respectively. Furthermore, possible mechanisms proposed on basis...

Abstract Background The Reform of medical insurance payment methods is one the crucial measures for controlling irrational practices. In China, National Health Insurance Administration requires a full switch from existing fee-for-service to DRG or DIP payments by 2025. Guangzhou, city with more developed economy and abundant resources in has completed reform local-insured patients since 2018. However, other-insured-region have not yet been included still retain payment. This paper intends...
Abstract Metal materials play an important role in electromagnetic interference (EMI) shielding due to their ultra‐high electrical conductivity, but they are rigid and inflexible, as well of high density, which limits application some areas. In this study, a novel simple method fabricate the composites metal foil polymer is reported. A copper (Cuf) with micropores on surface used matrix, then interpenetrating interlocking nanostructure reactive groups introduced its surface, silicone rubber...

Abstract Flexible all‐in‐one electrochromic fabrics (AECF) have attracted attention for application in wearable intelligent electronics. However, undifferentiated and disordered ion transport within the AECFs usually cause a slow transfer kinetics of reactive ions thus restrict their performance. Here, new strategy is proposed to optimize active based on well‐designed anion‐selective conductor (ASIC) boosting anionic AECF. The ASIC developed by interaction difference between electronegative...
