J. Lim et Yh. Kim, Stereoselective synthesis of 1 'beta-2 ',3 '-dideoxy-2 '-bis(ethoxycarbonyl)methyluridine nucleosides by ring opening of cyclopropanated glycals, J CHEM S P1, (22), 1999, pp. 3239-3241
Cyclopropanations of glycals followed by Lewis acid-mediated glycosylations
with 5-substituted uracils afforded 1'beta-2',3'-dideoxy-2'-bis(ethoxycarb
onyl)methyluridine nucleosides in a highly regiospecific and stereoselectiv
e manner in good yields.
