Urea, 1- 1-CYANO-3-ARYL

A -Cyano- and A -(p-toluenesulfonyl)-A -(trimethylsilylmethyl)-5-methylisothio-ureas 269a and 269b have also been utilized as synthetic equivalents of azomethine ylides. ° Reaction of 269a and 269b with aromatic aldehydes and aryl ketones, in the presence of CsF, gives 2-iminooxazolines 270a-e in modest-to-good yield. These 2-iminooxazolines apparently are stable to isolation and do not isomerize to 2-aminooxazolines (Scheme 8.76). [Pg.410]
