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.Cao, Ji; Tamura, Masazumi; Nakagawa, Yoshinao; Tomishige, Keiichi researched the compound: (2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol( cas:1824-94-8 ).COA of Formula: C7H14O6.They published the article 《Direct Synthesis of Unsaturated Sugars from Methyl Glycosides》 about this compound( cas:1824-94-8 ) in ACS Catalysis. Keywords: glycoside unsaturated synthesis catalyst deoxydehydration. We’ll tell you more about this compound (cas:1824-94-8).

Transformation of sugars without protection of the OH groups is an ideal method and a powerful tool for biomass utilization, and particularly, unsaturated sugars are a promising target because they can be transformed to versatile chems. because of the olefin group. Herein, we demonstrated direct transformation of various Me glycosides, which can be easily obtained from sugar derivatives, without protection of the OH groups to the corresponding unsaturated sugars with maintaining their original stereostructures in high selectivities and yields (up to 90%) using ReOx-Au/CeO2 catalyst at low H2 pressure (≤1.2 MPa) by deoxydehydration.

《Direct Synthesis of Unsaturated Sugars from Methyl Glycosides》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound((2R,3R,4S,5R,6R)-2-(Hydroxymethyl)-6-methoxytetrahydro-2H-pyran-3,4,5-triol)COA of Formula: C7H14O6.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 213697-53-1, C26H36NP.

Two new allyl complexes of palladium bearing the atropisomeric liganda 2-(diphenylphosphino)-2?-(dimethylamino)biphenyl (L1) and 2-(dicyclohexylphosphino)-2?-(dimethylamino)-biphenyl (L2) have been prepared and structurally characterized by X-ray crystallography. Their dynamic behavior as well as their structural characteristics in solution have been elucidated by the use of NMR techniques. Of particular interest, Pd-N bond rupture occurs with a low barrier ( < 10 kcal/mol) in the L1 complex; however, this does not provide a facile pathway for atropisomerization of the ligand. A coordination mode involving eta2 binding of carbon atoms in the (dimethylamino)phenyl moiety was also established for the dicyclo-hexylphosphino analogue L2. Interested yet?
