, p. 5579 - 5581 (2001)
Preparation of substituted pyrrolidines was achieved by solid-phase synthesis via a room temperature 1,3-dipolar cycloaddition of a silver-azomethine ylide, generated in situ, with a polymer-supported maleimide.

The first o-iodoxybenzoic acid (IBX) mediated oxidation of unactivated amines to imines is described. A range of meso-pyrrolidines were shown to be suitable substrates. The chemical space was further explored with one-pot oxidative Ugi-type and aza-Friedel-Crafts reactions, which proved to be highly diastereoselective.

A quinoline-functionalized norbornene (1) and its homopolymer (P1) for metal ions recognition have been synthesized and characterized. In CH3CN solution, 1 exhibited fluorescence enhancement response toward Hg2+, Zn2+ and Cu2+, with Hg2+ resulting in a green emission at 465 nm, and Zn2+/Cu2+ increasing 1's original emission at 406 nm. NMR titrations and DFT calculations results indicated that 1 bound Hg2+ in an imidic acid tautomeric form of the amide quinoline receptor, while Zn2+ and Cu2+ were bound to 1 in an amide tautomeric form. In addition, owing to the strong imidic acid tautomeric binding mode of 1-Hg2+ complex, 1 can recognized Hg2+ from Zn2+/Cu2+ and other competitive metal ions. In contrast, the homopolymer P1, which was obtained by ring opening metathesis polymerization (ROMP) method, exhibited only fluorescence enhancement sensing to Hg2+ and Cu2+ in an amide tautomeric binding mode with increasing emission at 416 nm.
