S. Kim et al., RADICAL CYCLIZATION OF N-AZIRIDINYLIMINES 4 - HIGHLY EFFICIENT SYNTHESIS OF DL-PENTALENENE VIA CONSECUTIVE CARBON-CARBON BOND FORMATION APPROACH, Synlett, (9), 1998, pp. 981
dl-Pentalenene, an angular triquinane, has been synthesized via tandem
radical cyclization of N-aziridinylimine 10 involving the formation o
f consecutive carbon-carbon bonds.
