A NEW TRIMETHYLSILYL TRIFLATE-CATALYZED 1,3-DIPOLAR CYCLOADDITION LEADING TO PYRROLIDINES
Achiwa, Kazuo,Sekiya, Minoru
, p. 2589 - 2592 (1982)
Pyrrolidines were obtained by a new, trimethylsilyl triflate-catalyzed cycloaddition of an intermediary N-trimethylsilylated methylene-iminium ylide, a 1,3 dipole, to olefinic and acetylenic dipolarophiles.
