Cai, Qun published the artcileI2-promoted tandem cyclization to synthesize polysubstituted pyrano[3,2-c]chromene-2,5-diones, Recommanded Product: 3-Acetylthiophene, the main research area is aryl ethanone hydroxycoumarin iodine tandem iodination Kornblum oxidation heterocyclization; hydroxybenzoyl aroyl pyranochromene dione preparation.
An efficient and convenient method for the synthesis of various substituted pyrano[3,2-c]chromene-2,5-diones was developed via the I2-promoted tandem cyclization of com. available aryl Me ketones and 4-hydroxycoumarins. Preliminary mechanism studies indicated that the reaction involved a consecutive iodination/Kornblum oxidation/annulation process. HI produced in the I2-DMSO system acted as an important promoter, accelerating the annulation protocol.
Tetrahedron published new progress about Aryl ketones Role: RCT (Reactant), RACT (Reactant or Reagent). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Recommanded Product: 3-Acetylthiophene.
