Beschreibung

Anwendung

A novel highly enantioselective allyl-transfer reagent. Excellent regio-, diastereo-, and enantioselectivities (usually >95% ee, >95% de) are obtained for the addition of allyl nucleophiles to aldehydes.[1][2][3][4] Although this reagent is used in stoichiometric amounts, the chiral ligand and monocyclopentadienyltitanium trichloride can be easily recovered.[5]

Verpackung

Bottomless glass bottle. Contents are inside inserted fused cone.
