General description
This support is useful for the production of peptide aldehydes and other carboxaldehydes. Following removal of the Fmoc group with 20% piperidine in DMF, acylation of the resin-bound methoxylamine is best effected using DIPCDI/HOAt or HATU/DIPEA activation. This results in formation of a supported Weinreb-type amide which can be either reduced to an aldehyde with LiAlH4 [1,2] or cleaved with Grignard reagents to give ketones [2,3].
