Synthesis and enzymatic resolution of amino acid esters in "green" solvents -- ionic liquids
… for obtaining optically pure amino acids by enzymatic resolution using a "green" solvent, named an ionic liquid. Ionic liquids, a new type of "green" solvents, have been used in many organic reactions and other chemical processes (such as liquid-liquid extraction) with improved performance. …

A new cyclohexyl-based chiral auxiliary: application in the total synthesis of (+)-linalool oxide
… resolve the racemic auxiliary (±)-TTC including enzymatic resolution and classical resolution. A successful classical resolution was achieved and the enantiomer (–)-TTC was obtained in excellent yield and enantiopurity (99 % ee). The stereochemistry of the obtained enantiomer was defined as …

Mechanistic investigation of the interrupted Bischler-Napieralski reaction and its application to the total synthesis of the aspidosperma alkaloids
… and (+)-limaspermidine. A highly effective enzymatic resolution of a non-[beta]-branched primary alcohol (E=22) allowed rapid preparation of both enantiomeric forms of a C21-oxygenated precursor for synthesis of these aspidosperma alkaloids. III. Development of an Ortho-Acetoxylation of …
