Md. Mihovilovic et al., Application of dry-state adsorption condition (DSAC) Pauson-Khand cyclization for the synthesis of perhydrocyclopenta[c] pyrroles, ARKIVOC, 2, 2001, pp. 1071-1076
A simplified protocol of dry-state adsorption condition (DSAC) Pauson-Khand
cyclizations for the preparation of the title compounds and the synthesis
of a variety of perhydro-cyclopenta[c]pyrrolones, are reported. In one case
the formation of a monocyclic compound was observed in varying amounts dep
ending on the reaction atmosphere.
