Yu, Longhui; Liu, Jun; Wang, Hongyu; Xu, Lijun; Wu, Yufei; Zheng, Changwu; Zhao, Gang published the artcile< Asymmetric Dieckmann Condensation towards Spirocyclic Oxindoles Catalyzed by Amino Acid-derived Phosphonium Salts>, Recommanded Product: 5,6-Dimethoxyisobenzofuran-1(3H)-one, the main research area is oxoindolinyl methylbenzenecarboxylate phosphonium salt catalyst enantioselective Dieckmann condensation; spiroindeneoxindole preparation.
An asym. Dieckmann condensation towards spirocyclic oxindoles and aza-oxindoles catalyzed by amino acid-derived phosphonium salt was developed, which expanded the applicability of asym. phosphonium salt catalysis in the production of 1,3-dicarbonyl compounds This reaction was distinguished by its mild conditions (-20°C), low catalyst loading (3-5 mol%), and broad substrate scope (25 examples). Control experiments revealed that both the catalyst’s phosphonium skeleton and H-bonding site were required. Product transformations and a gram scale experiment were also carried out.
Advanced Synthesis & Catalysis published new progress about Aryl iodides Role: RCT (Reactant), RACT (Reactant or Reagent). 531-88-4 belongs to class benzofurans, and the molecular formula is C10H10O4, Recommanded Product: 5,6-Dimethoxyisobenzofuran-1(3H)-one.
