一般描述

(S)-SDP is a chiral diphosphine reagent used in the asymmetric hydrogenation of ketones catalyzed by transition metal. It is also used in hydrosilylation or cyclization of 1,6-enynes.

应用

(S)-SDP can be used:

As a ligand in the ruthenium-catalyzed asymmetric hydrogenation of cyclic ketones to give cycloalkanols.
To prepare ruthenium complexes, which are used in the asymmetric hydrogenation of different prochiral ketones.
