An efficient synthesis of 3-cyano-3-benzoyloxyoxindoles via cyanoacylation of isatins in the presence of 4 Å molecular sieves
Year: 2012
Abstract:
In the presence of 4 Å molecular sieves in CH3CN, a process for the cyanobenzoylation and cyanocarbonylation
of isatins with benzoycyanides and ethylcyanoformate under mild reaction conditions has been
developed. ...
