Zusammenfassung:The present invention relates to a method for synthesis of optically pure 4-alkenyl or 4-alkanyl-2-hydroxytetronic acids from an optically pure aldehyde. The invention further relates to the use of such optically pure compounds as potent inhibitors of platelet aggregation by working at the level of cyclooxygenase, thus making them useful in the treatment of coronary artery diseases, especially atherosclerosis, and additionally, as inhibitors of various inflammatory cytokines, making them useful in the treatment of both acute and chronic inflammation, as well as in the treatment of cachexia, rheumatoid arthritis, multiple sclerosis, Crohn's disease and ulcerative colitis. The invention further relates to pharmaceutical compositions of the instant compounds. La presente invencion se refiere a un método para síntesis de ácidos 4-alquenil o 4-alcanil-2-hidroxitetronicos opticamente puros a partir de un aldehído opticamente puro. La invencion se refiere además al uso de dichos compuestos opticamente puros como inhibidores potentes de agregacion de plaquetas trabajando al nivel de ciclooxigenasa, haciéndolos así utiles en el tratamiento de enfermedades de arteria coronaria, especialmente aterosclerosis, y adicionalmente como inhibidores de varias citosinas inflamatorias, haciéndolas utiles en el tratamiento tanto de inflamacion aguda como cronica, así como en el tratamiento de caquexia, artritis reumatoide, esclerosis multiples, enfermedad de Crohn y colitis ulcerativa. La invencion se refiere además a composiciones farmacéuticas de los presentes compuestos.
