title: Synthesis and reactivities of 2,2'-anhydro-1-(3'-deoxy-3'-iodo-5'-O-trityl- beta-D-arabinofuranosyl)thymine.
abstract: 2,2'-Anhydro-1-(3'-deoxy-3'-iodo-5'-O-trityl-beta-D-arabinofuranosyl) thymine (2) was synthesized from 2',3'-didehydro-3'-deoxythymidine (DHT). Compound 2 was readily converted into the 2',3'-anhydrolyxofuranosyl derivatives 4-6. Treatment of 4a with some nucleophiles (N3-, OMe-, Cl-) gave the corresponding 3'-substituted arabinosyl nucleosides (7a,c,e) together with the minor xylosyl isomers (8a,c,d). 7a,c,e were deprotected to 7b,d,f, respectively.
