The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8 ) is researched.Application of 36620-11-8.Chen, Ziyi; Yin, Xuguang; Dong, Xiu-Qin; Zhang, Xumu published the article 《Efficient access to chiral dihydrobenzoxazinones via Rh-catalyzed hydrogenation》 about this compound( cas:36620-11-8 ) in RSC Advances. Keywords: benzoxazinone dihydro preparation enantioselective; benzoxazinylidene acetate ester hydrogenation rhodium catalyst. Let’s learn more about this compound (cas: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.
Although many compounds look similar to this compound(36620-11-8)Application of 36620-11-8, numerous studies have shown that this compound(SMILES:[F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10), has unique advantages.
