medicinal chemistry and natural products. Herein, we report that an exceptionally simple and inexpensive FeII complex efficiently catalyzes the direct transformation of simple alkenes into unprotected amino alcohols in good yield and perfect regioselectivity. This new catalytic method was applied in the expedientsynthesis of bioactive molecules and could be extended to aminoetherification.

A series of functionalized aryl boronic acids were synthesized and evaluated as potential inhibitors of factor XIa. Crystal structures of the protein-inhibitor complexes led to the design and synthesis of second generation compounds showing single digit micromolar inhibition against FXIa and selectivity against thrombin, trypsin, and FXa.
Self-assembly of oxidation-responsive polyethylene glycol-paclitaxel prodrug for cancer chemotherapy
Amphiphilic drug conjugates can self-assemble into nanovehicles for cancer drug delivery, but the key is to design stable yet intracellular labile drug linkers for drug retention during blood circulation but fast intracellular drug release. The conjugation of paclitaxel (PTX) is generally via the ester of its 2'-hydroxyl group, but the ester is either too stable to release PTX in the cytosol or so
