So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Miro, Roger; Cunillera, Anton; Margalef, Jessica; Lutz, Domke; Borner, Armin; Pamies, Oscar; Dieguez, Montserrat; Godard, Cyril researched the compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane( cas:97739-46-3 ).Reference of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.They published the article 《Rh-Catalyzed Asymmetric Hydroaminomethylation of α-Substituted Acrylamides: Application in the Synthesis of RWAY》 about this compound( cas:97739-46-3 ) in Organic Letters. Keywords: rhodium catalyzed asym hydroformylation hydroaminomethylation acrylamide sugar phosphoramidite ligand. We’ll tell you more about this compound (cas:97739-46-3).
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.
