A NEW TRIMETHYLSILYL TRIFLATE-CATALYZED 1,3-DIPOLAR CYCLOADDITION LEADING TO PYRROLIDINES
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.
Trimethylsilyl Triflate-Catalyzed 1,3-Dipolar Cycloaddition Leading to N-Unsubstituted Pyrrolidines
Dipolar cycloaddition of an intermediary N-trimethylsilyltrimethylsilylmethyliminium salt formed from N-(benzylidene)trimethylsilylmethylamine by the catalytical action of trimethylsilyl triflate to conjugated alkene or alkyne gave N-unsubstituted pyrroli
