Visible-light-promoted azidation/arylation of unactivated alkenes with Togni-N electron donor-acceptor complexes.

A visible-light-promoted azidation/arylation of unactivated alkenes with Togni-N has been achieved, leading to a series of azidated pyrrolo[1,2-]indoles under photocatalyst-free conditions. Notably, an EDA complex derived from the electron-rich indole derivatives and Togni-N served as the key intermediate in this reaction.

Base-promoted cascade 5- annulation/carboxylation of -(1-alkynyl)benzenesulfonamides with CO: divergent synthesis of mono- or -dicarboxylic esters.

A base-promoted cascade 5- cyclization/carboxylation of -alkynylsulfamides with CO has been accomplished, furnishing a variety of benzosultam-containing acrylates in good yields by using CO as the carboxylic source. Notably, in the case of substrates bearing a TMS-alkyne motif, the -dicarboxylation products were generated unprecedentedly.

Transcriptome-wide identification of walnut PP2C family genes in response to external stimulus.

Walnut is an important economic tree species while confronting with global environmental stress, resulting in decline in quality and yield. Therefore, it is urgent to elucidate the molecular mechanism for the regulation of walnut response to adversity. The protein phosphatase 2C (PP2C) gene family participates in cellular processes in eukaryotes through reversible phosphorylation of proteins and signal transduction regulation.
