| titleOfInvention | Process for the preparation of optically active 4 substituted (S)-2-oxazolidinone, optically active (S)-aminoalcohols and utilization of there compounds |
| abstract | 2.1. Process for the preparation of optically active, 4-substituted (S) -2-oxazolidinones of the general formula (IV) where R stands for a space-filling, branched, at least one tertiary carbon atom-containing alkyl group with 5 - 10 carbon atoms has not been disclosed to date.n n n 2.2. The fact that an optically active (S) -amino alcohol of the general formula (III) in which R represents a bulky, branched alkyl group containing at least one tertiary carbon atom and having 5 to 10 carbon atoms, acylated with a chloroformate on nitrogen and the intermediate with a catalytic effective amount of a base is cyclized to the corresponding (S) -2-oxazolidinone of the formula (IV), the desired products can be prepared in high purity and good yield. Compounds of the formulas (III) and (IV) are new.n n n 2.3. Pharmaceutical intermediates, asymmetric synthesis. |
