✦ Synopsis

A method for the synthesis of deuterium-labelled tryptophan and its enzymatic conversion to indole-3-pyruvic acid ( ( Hs) IPyA) using amino acid oxidase is described. an internal standard for the quantitation of IPyA by mass spectrometry in plant extracts and for estimating the breakdown of IPyA to indole-3-acetic acid (IAA) during sample extraction and purification. (2H5)IPyA should allow more accurate quantitation of IAA in plant extracts. 2 (2H5)IPyA can be used as When used in conjunction with (2H2)IAA, 1325

Synthesis of 5H-Pyrazino(2,3-b)indoles from Indole-2,3-dione Derivatives. -The reaction of the N-acetylisatins (I) with ethylenediamine yields the products (III). After dehydrogenation these compounds and their analogues (IV) after deacetylation are cyclized by heating to the title products (VI). N
