In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Rh-Catalyzed Asymmetric Hydroaminomethylation of α-Substituted Acrylamides: Application in the Synthesis of RWAY, published in 2020-11-20, which mentions a compound: 97739-46-3, Name is 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, Molecular C16H21O3P, Quality Control of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.
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.
In some applications, this compound(97739-46-3)Quality Control of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
