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 Jadhav, Prakash D., once mentioned the application of 18996-35-5, Name is Sodium 3,4-dicarboxy-3-hydroxybutanoate, molecular formula is C6H7NaO7, molecular weight is 214.11, MDL number is MFCD00013067, category is benzisoxazole. Now introduce a scientific discovery about this category, Recommanded Product: 18996-35-5.
This work describes two distinct annulations between ynamides and 1,2-benzisoxazoles with chemo-selectivity controlled by ligands. With IPrAuCl/AgNTf2, aryl-substituted ynamides undergo [5+2]-annulation reactions, whereas P(t-Bu)(2)(o-biphenyl)AuCl/AgNTf2 alters the chemoselectivity of the same ynamides to implement [5+1]-annulation reactions. C-13-Labeling experiments confirm that a 1,2-sulfonamide shift is involved in the [5+1]-annulation process. A plausible mechanism is postulated to rationalize the mechanisms of the two annulations.
