I2-Promoted [3+2] Cyclization of 1,3-Diketones with Potassium Thiocyanate: a Route to Thiazol-2(3H)-One Derivatives

An I2-promoted strategy has been developed for the synthesis of thiazol-2(3H)-one derivatives from 1,3-diketones with potassium thiocyanate. This [3+2] cyclization reaction involves C?S and C?N bond formation and exhibits good functional group tolerance. A series of thiazol-2(3H)-one derivatives are obtained in moderate to good yields. (Figure presented.).

Direct synthesis of 2,3,5-trisubstituted pyrroles: via copper-mediated one-pot multicomponent reaction

We have developed a copper-mediated one-pot synthesis of 2,3,5-trisubstituted pyrroles from 1,3-dicarbonyl compounds and acrylates using ammonium acetate as a nitrogen source. The reaction achieves C-C and C-N bond formation and provides an efficient approach to access highly functionalized pyrroles without further raw material preparation. This method is operationally simple, compatible with a wide range of functional groups, and provides the target products in moderate to good yields. This journal is

Preparation method and application of visual long-wave Hg fluorescent probe based on benzopyran

The invention discloses a preparation method and an application of a visual long-wave Hg fluorescent probe based on benzopyran. The prepared benzopyran derivative fluorescent probe takes dicyanomethylene-4H-benzopyran as a fluorophore, an azathiacrown ether unit serves as a main identification portion of metal ions, the visual long-wave Hg fluorescent probe usable for detecting Hg is synthesized, has remarkable large Stokes shift (120nm) and rapidly respond to mercury ions. In addition, after Hg is added, the color of probe solution is turned into yellow from bright rose red, and the probe can be used as a naked-eye visual probe. The design thinking can provide great help for development and identification of color matching of other target analytes and near-infrared fluorescent probes, and has an excellent application prospect.
