Beschreibung

Anwendung

Both (+)- and (-)-DIP-chloride are used for asymmetric reduction of prochiral ketones and for the preparation of β-amino alcohols.

Reagent used for an enantioselective reduction of (chloroacetyl) benzofurans to chlorohydrins which serve as intermediates for the corresponding epoxides and aminoalcohols. For a short paper on the preparation of DIP halides and their use in stereoselective reductions see Chem. Commun. 1053 (1994).
