The objective of the research described herein was to develop a simple traceless linker that could be used for bidirectional elaboration from a central nitrogen atom. To this end we have extended the usefulness of polymer-supported hydroxylamine. This linker has previously been described by others and has been used in the synthesis of tripeptide and sulfonamido hydroxamic acid derivatives, 3 and in the synthesis of a range of carbonyl-containing compounds. 4 An N- ...
