The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. This type of reactivity has quickly become one of the cornerstones of modern catalysis . 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Article，once mentioned of 14215-68-0, Product Details of 14215-68-0
GalNAc (1) was straightforwardly prepared from GlcNAc (2a) in six steps. Selective protection of the hydroxy groups on the C-1, C-3, and C-6 positions at the same time was performed by the treatment of TBDPS chloride (5.5 eq.) in DMF in 70% yield. The nucleophilic attack with CsOAc or KOBz on the chloromethylsulfonyloxy group at C-4 worked well (69-77% yield), accompanied by an unexpected rearrangement, to give the furanose products (6). The deprotection of all silyl and acyl groups under acidic conditions and the re-acetylation provided GalNAc (1) in 51% yield.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 14215-68-0, you can also check out more blogs about14215-68-0
