Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Angewandte Chemie, International Edition called Asymmetric Synthesis and Application of Chiral Spirosilabiindanes, Author is Chang, Xin; Ma, Pei-Long; Chen, Hong-Chao; Li, Chuan-Ying; Wang, Peng, which mentions a compound: 32305-98-9, SMILESS is CC1(C)O[C@@H](CP(C2=CC=CC=C2)C3=CC=CC=C3)[C@H](CP(C4=CC=CC=C4)C5=CC=CC=C5)O1, Molecular C31H32O2P2, Category: esters-buliding-blocks.
Reported here is the development of a class of chiral spirosilabiindane scaffolds by Rh-catalyzed asym. double hydrosilation, for the 1st time. Enantiopure SPSiOL (spirosilabiindane diol), a new type of chiral building block for the preparation of various chiral ligands and catalysts, was readily prepared on >10 g scale using this protocol. The potential of this new spirosilabiindane scaffold in asym. catalysis was preliminarily demonstrated by development of the corresponding monodentate phosphoramidite ligands (SPSiPhos), which were used in both a Rh-catalyzed hydrogenation and a Pd-catalyzed intramol. carboamination.
In addition to the literature in the link below, there is a lot of literature about this compound((((4R,5R)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine))Category: esters-buliding-blocks, illustrating the importance and wide applicability of this compound(32305-98-9).
