Chemistry is traditionally divided into organic and inorganic chemistry. COA of Formula: C17H19NO. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent,Which mentioned a new discovery about 112068-01-6

Novel P-stereogenic bis-phosphoramidite pincer palladium complexes 1 and 2 derived from (S)-(-)-alpha,alpha-diphenyl-2-pyrrolidinemethanol and (S)-(+)-indolinemethanol, respectively, were synthesized in reasonable yields (i.e., 55-62%) by using a flexible, modular synthetic approach and were characterized by X-ray crystal structure determination. Reacting (S)-(+)-indolinemethanol with PCl3 leads to the formation of a novel P-chiral building block, which exhibits good thermal stability of its stereochemical features. This enabled the design and development of new P-chiral bisphosphoramidite pincer arene ligands and their corresponding metal complexes. The molecular structure of the new indolinemethanol-derived phosphoramidite pincer metal complex screens quadrants I and III, which is in contrast to the previously reported L-proline-derived P-chiral ligands that screen quadrants II and IV. The bis-phosphoramidite pincer palladium, complexes 1 and 2 are active catalysts for asymmetric homoallylation of sulfonimines, where low (ee 33%) or no enantioselectivity was observed for reactions catalyzed by 2 and 1, respectively. Preliminary catalytic results revealed that enantiomeric excess values varied by using differently functionalized sulfonimines, suggesting that, both electronic properties and steric congestion of sulfonimines affect, the transition state of the electrophilic attack of the 1nallyl Pd intermediate in the allylation.
