N-LINKED HYDROXYLAMINE RESIN: SOLID-PHASE SYNTHESIS OF HYDROXAMIC ACIDS

Zheng Yin, KaySiang Low, and PekLing Lye

S*BIO Pte Ltd., Singapore

A novel hydroxylamine resin for solid-phase synthesis of hydroxamic acids is described. Its facile application is illustrated by the solid-phase synthesis of various hydroxamic acids. Cleavage is induced under acidic conditions by treatment with trifluoroacetic acid, providing hydroxamic acids in high purity and good yields.
