Abstract An asymmetric Darzens reaction of aldehydes with diazo- N,N -dimethylacetamide (3) catalyzd by an air-stable and storable chiral zirconium Lewis acid catalyst, which is formed from 3,3,-diiodobinaphthol and tetrabutoxyzirconium, gives solely the cis -glycidic amides in high yields with excellent enantioselectivity (up to 97% yield, >99% ee).

Titanverstärkt: Die Titelreaktion wurde durch einen chiralen Titankomplex katalysiert, der in,situ aus käuflichem Ti(OiPr)4 und (R)-Binol gebildet wurde, und lieferte mit ausgezeichneter Enantiomerenreinheit cis -Glycidamide (siehe Schema). Mit dieser neuen Methode wurden chirale Bausteine für die Synthese der Seitenketten von Taxol und (,)-Bestatin hergestellt. [source]
