(((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) (cas: 37002-48-5) belongs to chiral phosphine ligands. Although many reactions require more nucleophilic trialkylphosphines as catalysts, only a few chiral trialkylphosphines are available. Over the last decade, however, and especially since 2005, considerable progress has been made in asymmetric phosphine catalysis.Quality Control of (((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)

Nonenzymatic kinetic resolution of secondary alcohols: enantioselective SN2 displacement of hydroxy groups by halogens in the presence of chiral BINAP was written by Sekar, Govindasamy;Nishiyama, Hisao. And the article was included in Journal of the American Chemical Society in 2001.Quality Control of (((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine) This article mentions the following:

Cyclic secondary alcs. I (R = Ph, 2-MeC6H4, 3-MeC6H4, 4-MeC6H4, 4-MeOC6H4, 1-naphthyl, 2-naphthyl, cyclohexyl), phenylcyclooctanol II, and 1-phenyl-2-octadecanol undergo kinetic resolution by stereoselective nucleophilic displacement of secondary alcs. with chlorides in the presence of (S)-BINAP to give unreacted alcs. such as III in 82-97% yields and 69-98% ee and the inverted secondary chlorides IV in 56-94% ee. E.g., dehydrated THF was added to a mixture of I (R = Ph), 1 equivalent N-chlorosuccinimide, and 0.3 equivalent (S)-BINAP and the mixture stirred until the solution became clear; workup and chromatog. yielded (1R,2S)-III in 40% yield and 85% ee and (1R,2R)-IV in 42% yield and 89% ee in addition to the P,P’-dioxide of (S)-BINAP which was recovered in 92%. The enantioselectivity of the resolution was highly dependent upon the solvent used and the amount of chlorinating agent used; THF was the optimal solvent for the process and N-chlorosuccinimide as the chlorinating agent. 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: 37002-48-5Quality Control of (((4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene))bis(diphenylphosphine)).
