Compositions and methods for inhibiting translation are provided. Compositions, methods and kits for treating (1) cellular proliferative disorders, (2) non-proliferative, degenerative disorders, (3) viral infections, and/or (4) disorders associated with viral infections, using diaryloxindole compounds are described.
New C2-symmetric tetrafluorobenzobarreleneligands were prepared and applied successfully to the rhodium-catalyzedasymmetric addition of arylboronic acids to aromatic aldehydes giving chiral diarylmethanols in high yield with high enantioselectivity.
A process for producing an amine which is characterized by reacting an imine with a nucleophilic compound (except a trialkylsilyl vinyl ether) in the presence of a phosphoric acid derivative represented by the formula (1):
wherein A
1
represents a spacer; X
1
and X
2
represent each independently a divalent nonmetal atom or a divalent nonmetal atomic group; and Y
1
is oxygen or sulfur. The invention provides a process by which amines (particularly optically active amines) useful as intermediates of medicines, agricultural chemicals, or the like can be produced without special post-treatment in high yield at high optical purity; and phosphoric acid derivatives (particularly optically active phosphoric acid derivatives) useful in the production of the amines.
the synthesis of pillar[6]arenes was developed. A series of pillar[6]arenes were prepared with FeCl3 as catalyst and chloroform as solvent at room temperature in moderate yields (30%–40%). Their host-guest properties with n-cetyltrimethyl ammonium bromide were investigated by 1 HNMR. The results showed that high selectivity in the host-guest relationship became apparent between pillar[6]arenes and
