Tindall, Daniel J.; Mader, Steffen; Kindler, Alois; Rominger, Frank; Hashmi, A. Stephen K.; Schaub, Thomas published an article on January 11 ,2021. The article was titled 《Selective and Scalable Synthesis of Sugar Alcohols by Homogeneous Asymmetric Hydrogenation of Unprotected Ketoses》, and you may find the article in Angewandte Chemie, International Edition.Quality Control of (R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine The information in the text is summarized as follows:
Sugar alcs. are of great importance for the food industry and are promising building blocks for bio-based polymers. Industrially, they are produced by heterogeneous hydrogenation of sugars with H2, usually with none to low stereoselectivities. Now, we present a homogeneous system based on com. available components, which not only increases the overall yield, but also allows a wide range of unprotected ketoses to be diastereoselectively hydrogenated. Furthermore, the system is reliable on a multi-gram scale allowing sugar alcs. to be isolated in large quantities at high atom economy. The experimental part of the paper was very detailed, including the reaction process of (R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine(cas: 960128-64-7Quality Control of (R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine)
(R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine(cas:960128-64-7) is one of aminophosphine type ligands. An increased interest in aminophosphine type ligands used for asymmetric synthesis has been witnessed.Quality Control of (R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine This growth in popularity of aminophosphine ligands in asymmetric synthesis is in part due to the growing number of convenient synthetic pathways leading to useful ligand sets.
