The synthesis of thiazolo[3,4-a]pyridin-3-imines through the denitrogenative transannulation of pyridotriazoles with isothiocyanates using BF3·Et2O as a catalyst is described. A combination of solvents (dichlorobenzene-dichloroethane) plays a crucial role in obtaining the desired products under transition metal-free conditions.
描述了以BF 3 ·Et 2 O为催化剂,通过吡啶并三唑与异硫氰酸酯的脱氮环化反应合成噻唑并[3,4- a ]吡啶-3-亚胺。溶剂(二氯苯-二氯乙烷)的组合在无过渡金属条件下获得所需产品方面起着至关重要的作用。

Anticancer drug resistance implicates multifunctional mechanisms, and hypoxia is one of the key factors in therapeutic resistance. Herein, we report the development of AIE-active Cl− ion transporter which get activated under hypoxic environment.

A stimuli-responsive anion transport strategy was successfully employed to regulate the water solubility of ionophores and promote controlled transport of Cl− ions across lipid bilayers. A sulfonium-based proanionophore was efficiently activated by glutathione to regenerate the active anionophore, which allowed controlled transport of Cl− ions in a cellular environment with lower cytotoxicity.
