摘要

I of the proton (which was originally the 0-hydrogen of the enamine) in the zwitterionic intermediate (1) leads to its stabilization and to the products obtained by Stork. Our original purpose in the work described in this paper was to determine what course the reaction of electrophilic olefins with enamines containing no@-hydrogens would take. We found that reaction did indeed occur, leading to the formation of cyclobutanes, presumably via the ...
