Rhodium(III)-catalyzed remote meta-selective–C-H alkenylation of phenol derivatives has been developed using a traceless organosilicon template as the directing group. This transformation proceeds smoothly with good yields and high meta-selectivities toward a series of phenol and alkene substrates. In addition, this protocol provides an effective strategy for late-stage transformations of various meta-alkenylated

Catalyst-controlled diastereoselectivity in the fluorination of chiral allylic amines enabled the preparation of highly enantioenriched 1,3-difluoro-2-amines bearing threecontiguousstereocenters. The enantioselective catalytic method was applied successfully to other classes of multifunctional alkene substrates to afford anti-β-fluoropyrrolidines, as well as a variety of 1,2-oxyfluorinated products
The present invention provides compounds that are inducers or inhibitors of apoptosis or apoptosis preceded by cell-cycle arrest. In addition, the present invention provides pharmaceutical compositions and methods for treating mammals with leukemia or other forms of cancer or for treating disease conditions caused by apoptosis of cells.
