In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Efficient access to chiral dihydrobenzoxazinones via Rh-catalyzed hydrogenation, published in 2019, which mentions a compound: 36620-11-8, mainly applied to benzoxazinone dihydro preparation enantioselective; benzoxazinylidene acetate ester hydrogenation rhodium catalyst, Application of 36620-11-8.
Rh/(S)-DTBM-SegPhos-catalyzed asym. hydrogenation of prochiral (Z)-2-(2-oxo-2H-benzo[b][1,4]oxazin-3(4H)-ylidene)acetate esters I (R = 6-F, 5-CH3, 7-Cl, etc.; R1 = CH3, C2H5) was successfully developed. A series of chiral dihydrobenzoxazinones (R)-II was prepared through efficient methodol. with good to excellent results (up to >99% conversion, 93% yield and >99% ee), which are important motifs in the biol. active mols.
This literature about this compound(36620-11-8)Application of 36620-11-8has given us a lot of inspiration, and I hope that the research on this compound(Bis(norbornadiene)rhodium (I) tetrafluoroborate) can be further advanced. Maybe we can get more compounds in a similar way.
