Asymmetric Synthesis of 2-Amino-3-hydroxynorbornene-2-carboxylic Acid Derivatives.

Studies the enantioselective synthesis of 2-amino-3-hydroxynorbornene-2-carboxylic acid derivatives using Diels-Alder reaction between cyclopentadiene and different dienophiles, operating with different Lewis acids and both with thermal and with ultrasound conditions. Control of cycloaddition reaction in favor of the exo and endo products; Catalysts used in the reactions.
