Summary
Catalytic amounts of enantiopure aminoalcohols assist the decarboxylation of 2-carboxy-2-methyl-1-tetralone to 2-methyl-1-tetralone affording enantiomeric excesses of up to 35%. A rapid screening of the efficiency of various potential inductors of enantioselectivity has been carried out using circular dichroism spectroscopy.
Zusammenfassung
Katalytische Mengen von enantiomerenreinen Aminoalkoholen beschleunigen die Decarboxylierung von 2-Carboxy-2-methyl-1-tetralon. Es werden Enantiomerenüberschüsse von bis zu 35% erzielt. CD-Spektroskopie erlaubt eine schnelle Abschätzung der Effizienz von Aminoalkoholen und anderen Verbindungen als Katalysatoren für asymmetrische Reaktionen.
