Zugriff:
An efficient, metal-free approach to 3-substituted 3-hydroxyoxindole by DBU-mediated highly diastereoselective addition of aryl acetonitrile to N-protected isatin under mild conditions is developed. The reaction proceeds smoothly to produce respective cyanomethylated adducts in good yield and excellent diastereoselectivity.The mechanistic insight toward the aldol-type cyanomethylation of N-tritylisatin with benzyl cyanide is obtained by DFT calculations.
