Unprecedented Regio- and Stereoselective Synthesis of Pyrene-Grafted Dispiro[indoline-3,2 ‘-pyrrolidine-3 ‘,3 ”-indolines]: Expedient Experimental and Theoretical Insights into Polar [3+2] Cycloaddition
A series of dispiro[indoline-3,2′-pyrrolidine-3’,3 ”-indolines] was synthesized via a multicomponent polar [3 + 2] cycloaddition (32CA) reaction of isatin derivatives, sarcosine and (E)-3-(2-oxo-2-(pyren-1-yl)ethylidene)indolin-2-one derivatives. The regio- and stereochemistries of the cycloadducts were established on the basis of one-dimensional (1D) (H-1-, C-13-, C-13-CRAPT NMR) and two-dimensional (2D) homonuclear and heteronuclear correlation NMR spectrometry experiments (H-1-H-1 gDQFCOSY, C-13-H-1-HSQCAD, C-13-H-1-HMBCAD, H-1-H-1-ROESYAD). The molecular mechanism and regio- and stereoselectivities of the cycloaddition (CA) reaction have been investigated utilizing a density functional theory (DFT) method and were thoroughly explained based on the transition-state stabilities and global/local electrophilicity/nucleophilicity reactivity indices of the reactants.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 161596-47-0 is helpful to your research. Recommanded Product: 161596-47-0.
