Title: Preparation of 2-hydroxy-5-oxoproline and analogs thereof

Abstract

The compound 2-hydroxy-5-oxoproline and analogs thereof may be used to produce an increase in carbon dioxide fixation, growth, dry weight, nutritional value (proteins and amino acids), nodulation and nitrogen fixation and photosynthetically derived chemical energy when applied to plants through their roots and/or through their foliar portions. The present invention includes an essentially quantitative chemical synthesis for this compound which is performed in a single step reaction of Fremy's Salt (potassium nitrosodisulphonate) with either glutamine or 2-pyrrolidone-5-carboxylic acid. Fremy's salt (potassium nitrosodisulphonate) is available commercially, or can be readily synthesized.
