Synthesis of carbocyclic nucleosides from 2-azabicyclo[2.2.1]hept-5-en-3-ones: Sodium borohydride-mediated carbon-nitrogen bond cleavage of five- and six-membered lactams

Katagiri,Muto,Nomura,Higashikawa,Kaneko

, p. 1112 - 1122 (1991)

Various carbocyclic ribofuranosyl nucleosides were stereoselectively synthesized through a small number of steps from 2-azabicyclo[2.2.1]hept-5-en-3-ones by the use of sodium borohydride-mediated C-N bond cleavage as a key step. Ready availability of a no
