Guo, Rongwei; Lu, Shuiming; Chen, Xuanhua; Tsang, Chi-Wing; Jia, Wenli; Sui-Seng, Christine; Amoroso, Dino; Abdur-Rashid, Kamaluddin published an article on February 5 ,2010. The article was titled 《Synthesis of Chiral Aminophosphines from Chiral Aminoalcohols via Cyclic Sulfamidates》, and you may find the article in Journal of Organic Chemistry.Synthetic Route of C18H24NP The information in the text is summarized as follows:
Protic aminophosphines with multiple chiral centers were synthesized in good yields and high purity by the nucleophilic ring-opening of N-protected cyclic sulfamidates with metal phosphides, followed by hydrolysis and deprotection. This synthetic approach is clean, scalable, and high yielding. The method provides an efficient alternative route for the synthesis of chiral aminophosphines. In the experiment, the researchers used (S)-1-(Diphenylphosphino)-3,3-dimethylbutan-2-amine(cas: 286454-86-2Synthetic Route of C18H24NP)
(S)-1-(Diphenylphosphino)-3,3-dimethylbutan-2-amine(cas:286454-86-2) is one of aminophosphine type ligands. An increased interest in aminophosphine type ligands used for asymmetric synthesis has been witnessed.Synthetic Route of C18H24NP 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.
