π-Allylpalladium formation from allylic amines via N,N-ditosylimides and N-tosylamides: Efficient synthesis of the antiviral agent carbovir
Jung,Rhee
, p. 4719 - 4720 (1994)
Allylic amines can be easily converted into their N,N-ditosylimides or N-tosylamides which are sufficiently good leaving groups to afford π-allylpalladium complexes and, hence, with nucleophiles, new allylic systems with retention of configuration. The synthetic utility of this process has been demonstrated by an efficient synthesis of the antiviral agent (±)-carbovir (1) from cyclopentadiene in only seven steps and 13% overall yield.
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

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
