Opening of 2',3'-O-anhydro-ring of 2',3'-O-anhydro-lyxo-uridine by alkyl- and arylamines. Easy syntheses and preparative uses of 2'-deoxy-2'-alkylamino-xylo- and 3'-deoxy-3'-alkylamino-ara-uridines

Contrary to the previous report, under controlled conditions alkylamines, both primary and secondary and arylamines, opened the epoxide ring of 1-(5-O-trityl-2,3-O-anhydro-β-D-lyxo-furanosyl)-uracil to produce 2'-deoxy-2'-alkylamino-xylo- and 3'-deoxy-3'-
