Aminoalkohole, 1. Mitt.: Ein Verfahren zur Synthese enantiomerenreiner 1,2-Aminoalkohole miterythro-Konfiguration
摘要:
The synthesis of both enantiomers of norephedrine and norisoephedrine is described to present a method for the preparation of enantiomerically pure branched 1,2-aminoalcohols. In a one pot reaction enantiomerically pure cyanohydrins bearing an acetal protective group are subjected to Grignard-reaction followed by addition of lithium aluminum hydride. After deprotection the target compounds are obtained.
