Abstract: Chemiluminescence (CL) utilizing four-membered cyclic peroxides is one of the most useful analytical techniques. Up to now, the CL mechanisms for nonketone (1,2-dioxetanes) and monoketone (1,2-dioxetanones) derivatives of four-membered cyclic peroxides have been intensively studied… read more here.

Abstract: A general phase-transfer-catalyzed asymmetric (n+1) (n = 4 or 5) annulation reaction, featuring the direct coupling of simple oxindoles with alkyl dihalides that are allylic/benzylic and non-allylic/benzylic, has been developed to provide previously inaccessible cyclopentane-… read more here.

Abstract: The direct enantioselective vinylogous Michael addition of unsaturated γ-monosubstituted γ-lactams was realized by using chiral phase-transfer catalysis as a means to give enantioenriched γ,γ-disubstituted γ-lactams. read more here.
