A catalytic asymmetric bromocyclization of trisubstituted olefinic amides that uses a C(2)-symmetric mannitol-derived cyclic selenium catalyst and a stoichiometric amount of N-bromophthalimide is reported. The resulting enantioenriched pyrrolidine products, which contain two stereogenic centers, can undergo rearrangement to yield 2,3-disubstituted

Fourier transform infrared (FT-IR) spectra of phthalimide and N-bromophthalimide have been recorded in the range of 4000-400 cm-1. With the hope of providing more and effective information on the fundamental vibrations, a normal coordinate analysis has been performed on phthalimide

We report the site-selective bromination of vancomycin to produce, with substantial efficiency, previously unknown monobromovancomycins, a dibromovancomycin, and a tribromovancomycin. We document the inherent reactivity of native vancomycin toward N-bromophthalimide. We then demonstrate significant rate acceleration and perturbation of the
