  Synthesis of 2′,3″,4″-trisphosphate-containing analogs of adenophostin A

  摘要：

  Adenophostin A analog 4 was prepared via trimethylsilyl trifluoromethanesulfonate (TMSOTf)-assisted glycosylation of (S)-6-N-diphenylacetyl-9-(2-tert-butyldiphenylsilyloxy-1-hydroxyprop-3-yl)-adenine (11) with trichloroacetimidate donor 12 to give dimer 13. Protective group manipulations on 13 followed by phosphitylation with N,N-diisopropyl-bis-[2-(methylsulfonyl)ethyl] phosphoramidite (17) and in situ oxidation gave, after deprotection, (25)-9-{1-(alpha-D-glucopyranosyloxy 3,4-bisphosphate)-2-monophosphate-prop-3-yl}-adenine (4) Condensation of phosphoryloxymethyladenosine 25 with D-arabinitol derivative 21 under the agency of TMSOTf afforded methylene acetal 26. Protective group manipulations (--> 32), phosphorylation, and deprotection yielded 3'-O-(D-arabinitol-4-O-methylene 2,3-bisphosphate)-adenosine 2'-monophosphate (5), a methylene acetal-containing analog of adenophostin A.

• Towards the preparation of 2″-deoxy-2″-fluoro-adenophostin A. Study of the glycosylation reaction

  The synthesis of 2 ''-deoxy-2 ''-fluoro-adenophostin A framework starting from tri-O-acetylglucal and adenosine is described. The key steps are the formation of the 2-deoxy-2-fluoroglycosyl donor by electrophilic fluorination of tri-O-acetylglucal and the stereoselective glycosylation of a suitable adenosine derivative. The glycosylation reaction was optimized affording the desired 2 ''-deoxy-2 ''-fluoroglycoside with excellent alpha-stereoselectivity and in good yields, taking into account that glycosylations using nucleosides as glycosyl acceptors do not usually give excellent results. In that sense, an improvement of the glycosylation step with respect to that of the reported adenophostin synthesis, using adenosine derivatives as glycosyl donors, has been made.
