An efficient synthesis of polyoxamic acid utilizing the aryl group as the carboxyl synthon. A new approach to polyhydroxyamino acids
摘要:
Polyoxamic acid (1), an amino acid moiety of antifungal antibiotics polyoxins, has been efficiently synthesized from Boc-(R)4-hydroxyphenylglycine (3) utilizing its aryl group as the carboxyl synthon.
Stereoselective Synthesis of Polyoxamic Acid from (R)-Phenylglycine
摘要:
An efficient route for the synthesis of the biologically important amino acid, polyoxamic acid (1) has been developed via a syn selective Grignard reaction of vinylmagnesium bromide on (R)-N-Boc-phenylglycinal and utilization of the phenyl group as a masked carboxyl synthon.
