Jv. Barkley et al., STEREOSELECTIVE CONVERSION OF 2',3'-DIDEOXYDIDEHYDRO CARBOCYCLIC NUCLEOSIDES INTO 2'-DEOXY CARBOCYCLIC NUCLEOSIDES, Chemical communications, (10), 1998, pp. 1117-1118
Treatment of 2',3'-dideoxydidehydro carbocyclic nucleosides 5-9 with N
-bromoacetamide in AcOH gives bromoesters 10-14 with good stereocontro
l: debromination and hydrolysis furnishes 2'-deoxy carbocyclic nucleos
ides, e.g. 22.
