-
Paragraph 0029, (2017/04/28)
The invention discloses a method for preparing an alpha-acyloxy ketone compound. According to the invention, simple and easily available alcohol and carboxylic acid are taken as the raw materials, under mediation of NBS(N-bromo-succinimide) and DBU(1,8-diazabicyclo(5.4.0)undec-7-alkene), the alpha-acyloxy ketone is prepared by a one-pot reaction. The method has the advantages of mild reaction condition, simple and easily available raw materials, wide substrate adaptation scope, no requirement of rigorous reaction conditions such as any metal catalyst, peroxy compounds, low or high temperature and water-free and oxygen-free conditions, metal pollution is avoided; and the method also has the advantages of stable technical condition, simple and safe operation, and easy purifying of the product.

A metal-free protocol for the α-benzoxylation of ketones has been developed by using terminal aryl alkenes as an arylcarboxy surrogate. Moderate to good yields were attained for a variety of propiophenones and acetophenones by using tetra-n-butylammonium iodide (TBAI) as the catalyst and tert-butyl hydroperoxide (TBHP) as the oxidant under ambient reaction conditions. An efficient synthesis for the α-benzoxylation of aryl ketones has been developed by using terminal aryl alkenes as the arylcarboxy surrogate. The products were obtained in moderate to good yields for a broad scope of substrates. Tetra-n-butylammonium iodide (TBAI) and tert-butyl hydroperoxide (TBHP) were employed as the catalyst and oxidant, respectively.
