π-Allylpalladium formation from allylic amines via N,N-ditosylimides and N-tosylamides: Efficient synthesis of the antiviral agent carbovir

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.

Rearrangement of 2-Azabicyclohept-5-en-3-ones: Synthesis of cis-3-Aminocyclopentane Carboxylic Acid Derivatives

The γ-lactam 4 was converted into the bromo ester 6 and the latter compound was transformed in five steps into the diester 10.Similarly the lactam 4 was converted into the hydroxy amide 17 via the intermediacy of the dihalogeno compound 11.Compounds 10 an

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

STEREOSPECIFIC SYNTHESIS OF CARBOCYCLIC NUCLEOSIDES FROM 2-AZABICYCLO-HEPTAN-3-ONES VIA SODIUM BOROHYDRIDE MEDIATED CARBON-NITROGEN BOND CLEAVAGE

New synthons for carbocyclic nucleosides have been synthesized from 2-azabicyclohept-5-en-3-one readily available from cyclopentadiene, through introduction of an electron-withdrawing substituent at the 2-position followed by reduction with sodium
