Related Products of 97739-46-3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Rh-Catalyzed Asymmetric Hydroaminomethylation of α-Substituted Acrylamides: Application in the Synthesis of RWAY. Author is Miro, Roger; Cunillera, Anton; Margalef, Jessica; Lutz, Domke; Borner, Armin; Pamies, Oscar; Dieguez, Montserrat; Godard, Cyril.
The successful rhodium-catalyzed asym. hydroformylation and hydroaminomethylation of α-substituted acrylamides is described using 1,3-phosphite-phosphoramidite ligands based on a sugar backbone. A broad scope of chiral aldehydes and amines were afforded in high yields and excellent enantioselectivities (up to 99%). Furthermore, the synthetic potential of this method is demonstrated by the single-step synthesis of the brain imaging mol. RWAY.
As far as I know, this compound(97739-46-3)Related Products of 97739-46-3 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
