Recently I am researching about CYCLOADDITION; ARYLATION; CONSTRUCTION; REACTIVITY; EPOXYETHER; MECHANISM; ENAMIDES; ARYL, Saw an article supported by the Swiss National Science Foundation (SNSF)Swiss National Science Foundation (SNSF) [200020182798]; EPFL. Recommanded Product: m-Methoxyphenol. Published in WILEY-V C H VERLAG GMBH in WEINHEIM ,Authors: Declas, N; Waser, J. The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol
We report an Umpolung strategy of enol ethers to generate oxy-allyl cation equivalents based on the use of hypervalent iodine reagents. Under mild basic conditions, the addition of nucleophiles to aryloxy-substituted vinylbenziodoxolone (VBX) reagents, easily available in two steps from silyl alkynes, resulted in the stereoselective formation of substituted aryl enol ethers. The reaction was most efficient with phenols as nucleophiles, but preliminary results were also achieved for C- and N- nucleophiles. In absence of external nucleophiles, the 2-iodobenzoate group of the reagent was transferred. The obtained aryl enol ethers could then be transformed into alpha-difunctionalized ketones by oxidation. The described allyl cation-like reactivity contrast with the well-established vinyl-cation behavior of alkenyl iodonium salts.
