Advanced Synthesis &Catalysis, EarlyView.Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Advanced Synthesis &Catalysis, EarlyView.Abstract A modular synthesis of 2,3,4,6‐tetrasubstituted thieno[2,3‐c]furans, which employs a formal [3+2] cycloaddition utilizing the [1,2]‐phospha‐Brook rearrangement and a subsequent Brønsted base‐mediated cyclization, has been established, providing an efficient access to a wide range of densely functionalized thieno[2,3‐c]furans that are otherwise

Rapid and Scalable Halosulfonylation of Strain‐Release Reagents**
Angewandte Chemie, Volume 135, Issue 3, January 16, 2023., 2023 A one‐pot halosulfonylation of strained hydrocarbons is described that proceeds under practical, scalable and mild conditions. Sulfonyl halides featuring aryl, heteroaryl and alkyl substituents are generated in situ from sulfinate salts and convenient halogen atom sources. This chemistry enables the synthesis of an array of halogen/sulfonyl‐substituted

Oligomers of thieno[3,4-c]pyrrole-4,6-dione: Raman spectra [PDF]
, 2017 Oligothiophenes are π-conjugated compounds made by concatenation of thiophenes. [1] Due to the low aromaticity of thiophene, inter-ring π-electron delocalization is favored which has strong implication in their electro-optical properties and in their ...

Advanced Science, EarlyView.A reconfigurable microneedle electrode array integrated system is developed for minimally invasive and transdermal monitoring of subcutaneous electromyography, reactive oxygen species, and pH values. By assembling discrete thumbtack‐shaped microneedles into an array, the system enables multi‐parameter detection with single‐microneedle resolution.

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022 The single component flavin reductase/flavin dependent halogenase AetF catalyzes halogenation of a diverse set of substrates. High site selectivity, activity on relatively unactivated substrates, and high enantioselectivity for atroposelective bromination and bromolactonization was demonstrated.

Molecular Interlayer for High‐Performance and Stable 2D Tin Halide Perovskite Transistor
Advanced Science, EarlyView.Molecular interlayers are designed for p‐channel 2D Sn halide thin‐film transistors, yielding exceptional performance metrics, a significant reduction in hysteresis, and enhanced ambient stability. The effectiveness of new molecular interlayers (TPOF1, TPOF2, and 2F‐TOPF2) is confirmed by surface treatment, demonstrating remarkable carrier mobility ...

Thiazole formation through a modified Gewald reaction
Beilstein Journal of Organic Chemistry, 2015 The synthesis of thiazoles and thiophenes starting from nitriles, via a modified Gewald reaction has been studied for a number of different substrates. 1,4-Dithiane-2,5-diol was used as the aldehyde precursor to give either 2-substituted thiazoles or 2 ...
