WebApr 26, 2010 · Iron acquisition of graminaceous plants is characterized by the synthesis and secretion of iron‐chelating compounds, mugineic acids (MAs), and by a specific uptake system for MAs‐iron(III) complexes. We identified a transporter, HvYS1 (Hordeum vulgare L. yellow stripe 1), that is highly specific for MAs‐iron(III) in barley roots. In this article we … WebApr 15, 2011 · A highly practical stereoselective total synthesis of (-)-kainic acid is described. This synthesis features the stereoselective alkylation of an iodolactone intermediate that was efficiently prepared from (+)-carvone and introduction of carboxylic acid by hydrolysis of a nitrile accompanied by epimerizaion. This synthetic route enabled …
