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

  摘要：

  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.
