  Development of O–H insertion for the attachment of phosphonates to nucleosides; synthesis of α-carboxy phosphononucleosides

  摘要：

  Development of rhodium catalysed O-H insertion reactions employing alpha-diazophosphonates with appropriately protected adenosine, uridine and thymidine derivatives is described. This synthetic methodology leads, following deprotection, to novel phosphononucleoside derivatives bearing a carboxylic acid moiety adjacent to the phosphonate. Protection strategies are critical to the success of the key O-H insertion. There are two important aspects: avoiding competing insertion pathways or catalyst poisoning, and being able to achieve deprotection without degradation of the phosphononucleosides.
