(((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) (cas: 37002-48-5) belongs to chiral phosphine ligands. At present, the synthesis of new chiral phosphines designed specifically for nucleophilic organocatalysis remains a significant challenge. Over the last decade, however, and especially since 2005, considerable progress has been made in asymmetric phosphine catalysis.Reference of 37002-48-5

Highly Chemoselective Metal-Free Reduction of Phosphine Oxides to Phosphines was written by Li, Yuehui;Lu, Liang-Qiu;Das, Shoubhik;Pisiewicz, Sabine;Junge, Kathrin;Beller, Matthias. And the article was included in Journal of the American Chemical Society in 2012.Reference of 37002-48-5 This article mentions the following:

Unprecedented chemoselective reductions of phosphine oxides to phosphines proceed smoothly in the presence of catalytic amounts of specific Bronsted acids. By utilizing inexpensive silanes, e.g., PMHS or (EtO)2MeSiH, other reducible functional groups such as ketones, aldehydes, olefins, nitriles, and esters are well-tolerated under optimized conditions. In the experiment, the researchers used many compounds, for example, (((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) (cas: 37002-48-5Reference of 37002-48-5).
