Article Abstract
A novel bench-stable V-catalyst [(L)VO](ClO) was synthesized and characterized by X-ray diffraction (XRD) analysis and FT-IR, UV-visible, and EPR spectroscopies, which confirmed its excellent catalytic activity. In application, aldehydes are rapidly converted into their corresponding esters without additives in a one-pot manner using a newly developed catalyst [(L)VO](ClO) and HO as a green oxidant. The developed method is compatible with a broad range of densely substituted aldehydes and allows for the facile preparation of aliphatic, aromatic, and heterocyclic esters, including esters derived from CDOD, methanol, ethanol, -propanol, -butanol, -butyl alcohol, and propargylic alcohol. Gratifyingly, numerous alcohols also directly converted to their corresponding esters in a one-pot manner. We disclose herein the direct conversion of two different functionalities (alcohols and aldehydes) into esters (33 examples) with satisfactory yields, showing the potential of the developed catalyst toward varied oxidative organic transformations in a one-pot manner.

In this work, the previously reported SeODR strategy was used successfully for the synthesis of bicyclic peptides (). with different rings bearing various thioether linkages were prepared through a one-pot reaction; 15 with satisfactory yields were achieved. Cross-linkers including xylylene dibromide (, 2,6-bis(bromomethyl)pyridine (, 4,4'-bis(bromomethyl)biphenyl (), 1,3-dichloroacetone (, and dichloro--tetrazine ( are all compatible with the SeODR approach used for deprotection of the S-acetamidomethyl (Acm) group in peptides.

Semiconducting organic nanocrystals derived from the self-assembly of conjugated polymers hold great promise for optoelectronic applications. However, fabrication of these semiconductors with high uniformity and extended dimensions remains a major challenge due to tedious multistep procedures for size control and the formidable task of attaining crystal growth oriented perpendicularly to the π-π stacking direction. Here, we present a straightforward strategy for the preparation of uniform rectangular platelet micelles with tunable size through a single-step heating-cooling-aging protocol from conjugated poly(di--hexylfluorene) (PDHF) block copolymers (BCPs).

Rapid and controllable gelation of covalent organic framework (COF) materials with ordered accessible nanochannels is conducive to their use in versatile applications. However, challenges arise from intricate high-rate polymerization processes and unregulated phase separation, which complicate the fine management on equilibrium morphology and crystallinity in COFs. Herein, inspired by prevalent hydrogen bonding interactions in nature, a hydrogen bond exchange (HBE)-induced microphase separation (termed HBEiMS) pathway is proposed for the facile preparation of hydrazone-linked COF "A&B" gels.

Intramolecular [2 + 2] cycloaddition/dearomatization could be an ideal pathway to construct semi-saturated polycycles in a "one-pot" manner. However, such a reaction is considered as thermodynamically infeasible due to the instability of the cyclobutane-fused rings and the higher triplet-excited-energy barrier of substrates. Herein, we successfully achieved an array of semi-saturated alkaloid analogues─cyclobutane-fused indolizidines─in up to 98% yield for 33 examples through intramolecular [2 + 2] cycloaddition of indoles via high-energy diradical intermediates.
