N-Substituted 4,5,6-trihydroxy-α-aminohexanoic acidsOxidative decarboxylation of peracetylated welan gum (S-130) with lead tetraacetate resulted in selective cleavage of the glucuronosidic linkages. Products of the degradation were reduced with sodium borohydride, O-deacetylated, and fractionated. ...

Metal-catalysed reactions involving ammonia gas are plagued by ammonia’s strong Lewis basicity, which leads to poor chemoselectivity and enantioselectivity. Here we introduce a strategy for preparing chiral α-amino acids directly from ammonia. By the c
amino acids have amine and carboxylic acid groups •All are primary amines (R-NH 2 ) except proline Amine (base) + carboxylic acid = proton transfer possible: Neutral (unionized) form Zwitterionic (ionized) form K eq > 1 at physiological pH a-carbon •Side chains (R) vary •18 ...
