You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.10034-20-5, Name is (2S,3R,4R,5S,6R)-6-(Acetoxymethyl)-3-aminotetrahydro-2H-pyran-2,4,5-triyl triacetate hydrochloride, molecular formula is C14H22ClNO9. In a patent, introducing its new discovery.
Dual-participation protecting group solves the anomeric stereocontrol problems in glycosylation reactions
The 2,2-dimethyl-2-(ortho-nitrophenyl)acetyl (DMNPA) group permits, via robust neighboring group participation (NGP) or long distance participation (LDP) effects, the stereocontrolled 1,2-trans, 1,2-cis, as well as beta-2,6-dideoxy glycosidic bond generation, while suppressing the undesired orthoester byproduct formation. The robust stereocontrol capability of the DMNPA is due to the dual-participation effect from both the ester functionality and the nitro group, verified by control reactions and DFT calculations and further corroborated by X-ray spectroscopy.
