Aza-dipyrromethene boron difluoride(aza-BODIPY) has gained increased attention in the recent years due to their remarkable optical properties.1 Various methods have been developed to extend the π-conj
Isobenzofuran and naphthalene are important building blocks of the natural products and drugs,such as Pestacin 1,Escitalopram 2,Gossypol[1].Many methods are developed for the construction of isobenzof
The 1,3-dipolar cycloaddition reaction of an alkene or a diene with a nitrone is one of the most reliable strategies for construction of five-membered or seven-membered isoxazolidine derivatives.
The Povarov reaction of imine dienes with electron-rich dienophiles has been maturely developed.As for the electron-rich olefins,the alkenes adjacent to O or N heteroatom are widely used in the Povaro
The chroman-4-one scaffold with functional groups widely exists in natural products,and has found abundant applications in medicinal and biological compounds.
The reactions of Friedel-Crafts alkylation for indoles and imines have been reported continually.[1-3] And recently,our group has developed several novel cascade cyclization reactions of homopropargyl
Transition metal catalyzed cyclization of 1,n-enynes has now captured considerable attention of organic chemists,due to it allows the direct,rapid and efficient access to assemble a wide range of high
Due to its ability to simultaneously establish several stereogenic centers,desymmetrization has been widely recognized as one of the most important strategies in asymmetricsynthesis.
Ferrocene derivatives,because of their unique structural and electronic characters,have been extensively used in organic synthesis,materials science,and medicinal chemistry.
The use of asymmetric catalysis is a powerful,economically feasible tool for the preparation of optically active organic compounds on both laboratory and industrial scales.
