Synthesis of the Dimethyl Ester of 1‐Deoxy‐l‐Idonojirimycin‐1‐Methylenphosphonate: A New Approach to Iminosugar Phosphonates
摘要:
1-Methylenphosphonate-1-deoxy-L-idonojirimycin (1) has been synthesized starting from commercially available tetrabenzyl glucose, the key steps being substitution of the hydroxyl group at C-5 of compound 7 with an azido group, stereoselective reaction of the aldehyde at C-1 of compound 10 with dimethyl methylenephosphonate anion, conversion of the azide into an amino group, and finally cyclization of the aminoalcohol 12.[GRAPHICS]
