Palladium-catalyzed allylation of aminophenol with alkynes to construct C-N bonds.

A method for the allylic alkylation of aminophenol with alkynes was developed using a palladium-catalysed allylation reaction with 100% atom economy. A series of structurally diverse N-allylic substituted allylamines were synthesized in good yields with high chemo-, regio-, and stereoselectivities under mild conditions.

Synthesis of novel chiral tridentate Schiff-base ligands and their applications in catalytic asymmetric Henry reaction.

A series of chiral tridentate Schiff-bases were prepared and used as ligands in the catalytic asymmetric Henry reaction. Under the optimal conditions, a variety of arylaldehydes were smoothly converted into corresponding adducts with high yields (up to 98%) and excellent enantioselectivities (up to 97% ee).

Gold-catalyzed cascade reaction of hydroxy enynes for the synthesis of oxanorbornenes and naphthalene derivatives.

An efficient and selective gold-catalyzed cascade reaction for the synthesis of oxanorbornenes and naphthalene derivatives from easily prepared hydroxy enynes has been developed. Divergent products could be obtained from the same substrates by different gold catalytic systems.

2-[3-Acetyl-5-(2-chloro-3-pyrid-yl)-2-methyl-2,3-dihydro-1,3,4-oxadiazol-2-yl]-4-fluoro-phenyl acetate.

In the title compound, C(18)H(15)ClFN(3)O(4), the dihedral angle between the substituted pyridine ring and the oxadiazo-line ring is 9.73 (19)° and the acyl group is coplanar with the oxadiazo-line ring [O-C-N-C torsion angle = -2.1 (3)°]. Furthermore, the substituted benzene ring is almost orthogonal with the oxadiazo-line ring, the dihedral angle between them being 87.56 (18)°.

N-[3-(2-Methyl-phen-yl)isoquinolin-1-yl]formamide.

The title compound, C(17)H(14)N(2)O, crystallizes as a cis formamide isomer. The isoquinoline and benzene fragments are nearly perpendicular [dihedral angle = 81.79 (18)°], whereas the formamide group is virtually coplanar with the isoquinoline unit [dihedral angle = 1.66 (15)°]. Inter-molecular N-H⋯O hydrogen bonds link mol-ecules into a centrosymmetric dimer.

Pd-catalyzed synthesis of beta-biarylacryl ferrocenes via Suzuki cross-coupling.

Some novel beta-biarylacryl ferrocene derivatives were synthesized via Pd-catalytic Suzuki cross-coupling reactions of beta-(2-bromophenyl)acrylferrocene and arylboronic acids. The structures were determined with elemental analyses, IR spectra, and (1)H-NMR spectra.
