Porwanski, Stanislaw published an article in Carbohydrate Research. The title of the article was 《New ureas containing glycosyl and diphenylphosphinyl scaffolds: synthesis and the first attempts to use them in asymmetric synthesis》.Computed Properties of C22H22NP The author mentioned the following in the article:
Chiral ureas containing glycosyl and diphenylphosphinyl scaffolds, e.g. I, were found to be an effective organocatalyst. They were synthesized in high yields by a one-pot tandem Staudinger/aza-Wittig coupling reaction. The first attempts of using them in asym. synthesis are presented. Yields of the Morita-Baylis-Hillman reaction were moderate with an enantiomeric excess of up to 80%. In the part of experimental materials, we found many familiar compounds, such as (R)-8-(Diphenylphosphino)-1,2,3,4-tetrahydronaphthalen-1-amine(cas: 960128-64-7Computed Properties of C22H22NP)
(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.Computed Properties of C22H22NP 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.
