Synthesis of an azide-bearing N-mustard analogue of S-adenosyl-L-methionine.


PMID 22050725

Abstract

The synthesis of an azide-bearing N-mustard S-adenosyl-L-methionine (SAM) analogue, 8-azido-5'-(diaminobutyric acid)-N-iodoethyl-5'-deoxyadenosine, has been accomplished in 10 steps from commercially available 2',3'-isopropylidene adenosine. Critical to this success was executing C8 azidation prior to derivatizing the 5'-position of the ribose sugar and the late stage alkylation of the 5' amino group with bromoethanol, which was necessitated by the reactivity of the aryl azide moiety. The azide-bearing N-mustard is envisioned as a useful biochemical tool by which to probe DNA and protein methylation patterns.
