, p. 763 - 768 (2000)
The synthesis of acetylenic amides from 2-bromoaniline and propiolic acids followed by their cyclisation via the derived aryl radical is presented. Silylation of the terminal end of the triple bond is shown to be required for successful cyclisation to 3-methyleneindol-2(3H)-ones. The exocyclic double bond can be epoxidised using m-chloroperoxybenzoic acid (MCPBA). The Royal Society of Chemistry 2000.
