Strained azetidinium ylides: new reagents for epoxidation.
Azetidinium ylides effected facile epoxidation of various carbonyl compounds furnishing tri or tetrasubstituted epoxides that were unattainable via classical ammonium ylide chemistry; the produced trisubstituted oxiranes gave rise to a remarkable cascade of reactions leading to some original pyrrolidin-3-ones.
