Stereocontrolled hydroxymethylation of carbohydrate imines: Formal synthesis of destomic acid and lincosamine
摘要:
Addition of [(dimethylphenylsilyl)methyl]magnesium chloride to 6-benzylimino-6-deoxy-1,2;3,4-di-O-isopropylidene-alpha-D- galactopyranose mediated by Ce(III)Cl-3 or CuI/BF3.Et(2)O proceeds with complete syn- or anti-diastereoselectivity, respectively, to afford highly chiral precursors of destomic acid or lincosamine.
