Abstract
| - Arbuzov reaction of O-acetyl-protected glycosylthiomethyl chlorides with triethyl phosphite and thenphosphonate ethyl ester cleavage with trimethylsilyl bromide afforded glycosylthiomethyl phosphonates 13, 18, 22,and 26. These intermediates could be readily transformedinto the O-deprotected phosphonates 7−10 and into titlecompounds 1−4. Similarly, sulfonomethyl phosphonate moieties containing UDP-sugar analogues 5 and 6 were obtained.
