title: Mechanistic subtleties in the cyclopentannelation of allenolate allyl carbamates: the origin of the center-to-center chirality transfer.
abstract: The stereospecific rearrangement of allene carbamates i to alkylidenecyclopentenones iii is concerted, displays charge donation from the pi*(allenonate) to the sigma*(C-leaving group), and shows mechanistic features of both pericyclic and ionic processes, modulated in part by the degree of ionic interaction (O-...Li+) in the putative intermediate allenolate ii.
