Yn. Bubnov et al., SIMPLE SYNTHESIS OF BENZO[F]PYRROLIZIDINE AND BENZO[G]INDOLIZIDINE WITH THE USE OF PRODUCTS OF THE REDUCTIVE ALLYLATION OF INDOLE AND QUINOLINE, Russian chemical bulletin, 45(11), 1996, pp. 2665-2667
Benzo[f]pyrrolizidine and benzo[g]indolizidine were synthesized by hyd
roboration-oxidation-intramolecular cyclization of the corresponding p
roducts of the reductive alpha-allylation of indole (2) and quinoline
(6) with allylboranes.
