Synthesis of Tricholomic Acid. V. Synthesis of DL-Tricholomic Acid and Its threo-Isomer from Diastereoisomers of β-Hydroxyglutamic Acid through α-Mono Esters

Abstract

Racemic tricholomic acid and its threo-isomer (I) were prepared by a new route starting from the diastereoisomers of β-hydroxyglutamic acid (II) through α-mono esters (XI) and γ-benzyloxyamides (XIII).
