Investigations of Novel Azomethine Ylide-Forming Photoreactions of N-Silylmethylimides

The scope of a recently discovered (Yoon, E.C. et al.J.Am.Chem.Soc. 1995, 117, 2698), azomethine ylide-forming photoreaction has been explored by probing the excited state chemistry of several N-trimethylsilylmethyl substituted cyclic and acyclic imides and amide analogs.Photolysis of N-<(trimethylsilyl)methyl>maleimide (4) in acetonitrile leads to efficient production of the tricyclic product 16, formed by trapping of the photogenerated azomethine ylide intermediate 15 through cycloaddition with 4.Irradiation 4 in solutions containing high concentrations of the dipolarophiles, acrylonitrile or fumaronitrile, results in production of the products (19-21 and 23-24, respectively) arising by cycloaddition of the ylide 15 with the added dipolarophiles.In contrast, photolysis of the nonconjugated cyclic imide, N-<(trimethylsilyl)methyl>succinimide (5), brings about N-acyl migration resulting in the exclusive production of the unstable, iminolactone 30.On the other band, acyclic, N-trimethylsilylmethyl aroyl imides 6-8 undergo the excited state C to O silyl migration reaction to produce azomethine ylide intermediates 35.Both in the presence or absence of added dipolarophiles, these ylides undergo electrocyclization to form transient aziridine intermediates 36 which react further by ring opening to generate N-phenacylamide products 32-34.In contrast, the nonconjugated imide, N-<(trimethylsilyl)methyl>-N-acetylacetamide (9), is unreactive upon irradiation.Similarly, simple N-<(trimethylsilyl)methyl>amides 10-13, while being photochemically labile, do not react to form “trappable” ylide intermediates upon irradiation.The results outlined above are presented and discussed in terms of the scope and limitations of the new, azomethine ylide-forming photoreaction of silylmethyl imides.

Pyrrolidinohydroquinazolines – A novel class of CCR3 modulators

A novel class of CCR3 modulators is described. Starting with lead compound 4a (Ki: 110 nM), which turned out to be an antagonist of eotaxin at the CCR3 receptor, further optimization led to compound 8b (Ki: 28 nM), which surprisingly proved to be an agonist.

2,6-dimethoxyphenyl-substituted n-heterocyclic carbenes (NHCs): A family of highly electron-rich organocatalysts

Based on our recent finding that 2,6-dimethoxyphenyl-substituted NHCs show superior reactivity in the hydroacylation reactions of electron-neutral olefins compared with known NHCs, we now report the syntheses and crystal structures of four highly electron-rich 2,6-dimethoxyphenyl-substituted NHCs and show the increase in efficiency caused by the electron-rich aryl substituent in hydroacylation reactions. The synthesis and crystal structures of four highly electron-rich 2,6-dimethoxyphenyl-substituted NHCs are reported. These NHCs should have interesting applications as ligands or in NHC organocatalysis.
