Abstract
The subject invention involves processes for making hydroxamic acid compounds using a solid-support resin having an oxime moiety as the linking moiety of the resin, comprising the steps of (a) treating the resin with a carboxylic acid compound, such that it is attached to the resin by a condensation reaction between the oxime and carboxyl moieties; (b) optionally modifying the side chain; (c) cleaving a product from the resin by treating with O-tert-butyldimethylsilylhydroxylamine; (d) optionally modifying the side chain; and (e) optionally treating the resulting O-TBS-protected material with acid to produce an unprotected hydroxamic acid compound.
