Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Wang, Dan, once mentioned the application of 55750-62-4, Name is N-Succinimidyl 3-maleimidopropionate, molecular formula is C11H10N2O6, molecular weight is 266.21, MDL number is MFCD00043141, category is indole-building-block. Now introduce a scientific discovery about this category, SDS of cas: 55750-62-4.
Dual Palladium/Scandium Catalysis toward Rotationally Hindered C3-Naphthylated Indoles from beta-Alkynyl Ketones and o-Alkynyl Anilines
Main observation and conclusion A new dual palladium/scandium catalysis starting from beta-alkynyl ketones and o-alkynyl anilines is reported for the first time, leading to the atom-economic synthesis of rotationally hindered C3-naphthylated indoles in moderate to good yields and high regioselectivity. This method can tolerate normal air conditions, and features the use of palladium/scandium cooperative catalysts without any ligand, facile double annulation involving various internal alkynes, and good functional group tolerance.
