Anwendungen & Verwendung
Verwenden
N,N-Diisopropylethylamine is used as a base in organic reactions. Used in the preparation of (-)Gambierol a marine polycyclic ether toxin. It is also used in the synthesis of potent inhibitors of human brain memapsin, a key effector in the progression of Alzheimer’s disease.
Herstellung & Synthese
synthetische
N,N-Diisopropylethylamine is used as a non-nucleophilic base in organic synthesis. It is prepared by the alkylation of diisopropylamine with diethyl sulphate. DIPEA can then be purified through distillation from potassium hydroxide if necessary.
