HPLC analysis of the urine of autistic subjects indicated the presence of an unidentified component in greatly increased concentrations. We have reported the isolation of this component by HPLC and its identification. Mass spectrometry, NMR and UV spectroscopy identified the peak as corresponding to indolyl-3-acryloylglycine (IAG, 3), and this has been confirmed by an independent synthesis.

Copper complexes of 3-trifluoroacetyl-( +)-camphor and two of its derivatives give high optical yields when used as catalysts for the asymmetric cyclopropanation of styrene with 2-diazodimedone; an immobilised analogue of these homogeneous catalysts retains high activity, is readily recovered, and has potential for recycling.
