The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis. 82911-69-1, Name is N-(9-Fluorenylmethoxycarbonyloxy)succinimide, formurla is C19H15NO5. In a document, author is Hao, Wenyan, introducing its new discovery. HPLC of Formula: C19H15NO5.
A Highly Efficient Copper(I)-Catalyzed Cascade Reaction of o-Alkenylphenyl Isothiocyanates with Isocyanides Leading to 5H-Benzo[d]imidazo[5,1-b][1,3]thiazines
The highly efficient copper(I)-catalyzed cascade reaction of (E)-3-(2-isothiocyanatophenyl)acrylates and (E)-3-(2-isothiocyanatophenyl)acrylonitriles with isocyanides was explored. The method provides an expedient route for the synthesis of 5H-benzo[d]imidazo[5,1-b][1,3]thiazines in good to excellent yields by using CuCl (10 mol-%) as the catalyst and K3PO4 (2.0 equiv.) as the base in THF at 70 degrees C. The reaction involves [3+2] cycloaddition and subsequent intramolecular C-S bond formation.
