Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 59-48-3, Name is Indolin-2-one, SMILES is O=C1NC2=C(C=CC=C2)C1, belongs to indolines-derivatives compound. In a document, author is Zhu, Xun, introduce the new discover, SDS of cas: 59-48-3.
Green and Facile Synthesis of Spirocyclopentanes Through NaOH-Promoted Chemo- and Diastereo-Selective (3+2) Cycloaddition Reactions of Activated Cyclopropanes and Enamides
A chemo- and diastereo-selective (3 + 2) cycloaddition reacition between Donor-Acceptor (D-A) cyclopropanes and alpha,beta-unsaturated enamides is developed for efficient access to spiro(cyclopentane-1,3′-indoline) derivatives. Simple, inexpensive and readily available NaOH is used as the sole catalyst for this process. A broad range of D-A cyclopropanes could be used as the C-3 synthons to react with oxindole-derived alpha,beta-unsaturated enamides. The structurally sophisticated spiro(cyclopentane-1,3′-indoline) derivatives bearing up to 3 adjacent chiral centers are afforded in excellent yields as single diastereomers.
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 59-48-3 is helpful to your research. SDS of cas: 59-48-3.
