enantioselectivities and isolated yields have been achieved for the hydrolytickineticresolution of epoxidesusing a resin-supporteddendronized R,R-(salen)Co catalyst with catalyst loadings as low as 0.04 mol%, the lowest metal loadings of any heterogeneous resin-supported (salen)Co catalyst reported to date. In addition, the supported catalysts can be recycled and reused with comparable enantioselectivities

The invention relates to derivatives of glycopeptide and lipoglycopeptide antibiotics possessing an altered ionization state with respect to the parent glycopeptide or lipoglycopeptide antibiotic, and having the ability to be regenerated as the parent glycopeptide or lipoglycopeptide antibiotic under physiological conditions. These compounds are useful as antibiotics for the prevention and/or the treatment of bacterial infections.
