Abstract: An efficient and green reaction of isatins, 3-amino-1-phenyl-2-pyrazolin-5-one (3-amine-1H-pyrazole), and beta-diketone in aqueous medium in the presence of PEG ?SO 3H is reported, and a series of novel spirocompounds was obtained with high yields. The advantages of this reaction were simple procedure, moderate reaction conditions, and wide range of substrates. More importantly, the catalyst PEG ?SO 3H could be recovered for reuse up to five times. Graphical Abstract: [Figure not available: see fulltext.].

Electric Literature of 1679-47-6, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1679-47-6, molcular formula is C5H8O2, introducing its new discovery.

beta-Amino acids are routinely incorporated into peptidic drugs to increase their stability and to incur conformational biases. However, the synthesis of highly substituted beta-amino acids still represents a great challenge. A new approach to their preparation is reported involving a Vilsmeier-Haack reaction with nonaromatic carbon nucleophiles. The highly challenging preparation of contiguous tertiary and all-carbon quaternary centers was successfully used to generate several beta2,2,3-amino esters, such as derivatives of homoproline, homoalanine, and homopipecolinic esters.
