Preparation of indoles from α-aminonitriles: A short synthesis of FGIN-1-27
Opatz, Till,Ferenc, Dorota
, p. 4473 - 4475 (2007/10/03)
α-Aminonitriles derived from 2-aminocinnamic acid esters and amides can be cyclized under basic conditions to furnish substituted indole-3-acetic acid derivatives in quantitative yield. The reaction provides a simple access to a class of biologically acti
