Practical Asymmetric Henry Reaction Catalyzed by a Chiral Diamine-Cu(OAc)<sub>2</sub> Complex
The chiral diamine ligand 3 was designed and synthesized from (R,R)-1,2-diphenylethylenediamine, (S)-2,2‘-dibromomethyl-1,1‘-binaphthalene,
and o-xylylene dibromide. The resulting 3-Cu(OAc)2 complex was a highly efficient catalyst for the Henry reaction, giving the various nitroaldols
with over 90% ee (up to >99%). The reaction was performed in n-propyl alcohol at room temperature, and the Henry adducts were produced
in high yield with excellent enantiomeric excess; these attributes are desirable in a catalyst for practical use

Figure S3. mRNA expression of CCN members (CCN1, CCN2, CCN3, CCN4, CCN5, and CCN6) after exposure of AF cells to 6-bromoindirubin-3′-oxime (BIO) (1.0 μM) for 24 h assessed using real-time PCR. Results are presented as mean and 95% CI (n = 12 for each group). GAPDH was used as an endogenous control. The unpaired Student’s t test was used. (PDF 14 kb

A 2:1 Coupling Reaction of Arynes with Aldehydes via <i>o</i>-Quinone Methides: Straightforward Synthesis of 9-Arylxanthenes
A novel coupling reaction, where an aldehyde and two molar amounts of an aryne are assembled selectively, has been demonstrated to afford
diverse 9-arylxanthene derivatives in one step. o-Quinone methide arising from the [2 + 2] cycloaddition of an aldehyde with an aryne was
postulated as a transient intermediate
Asymmetric <i>Syn</i>-Selective Henry Reaction Catalyzed by the Sulfonyldiamine−CuCl−Pyridine System
A catalytic asymmetric Henry reaction has been developed with use of a sulfonyldiamine−CuCl complex as a catalyst. A series of new binaphthyl-containing sulfonyldiamine ligands (2a−h) were readily synthesized in two steps starting from commercially available chiral 1,2-diamines. The (R,R)-diamine-(R)-binaphthyl ligand (2d)−CuCl complex smoothly catalyzed the enantioselective Henry reaction with the assistance of pyridine to give the corresponding adduct with high enantiomeric excess (up to 93%). Moreover, the 2d−CuCl−pyridine system promotes the diastereoselective Henry reaction in syn-selective manner to give the adduct in up to 99% yield with 92:8 syn/anti selectivity. The enantiomeric excess of the syn-adduct was 84% ee

As we have reported previously [60], lamina I is relatively thick in this region. Images of pan-AMPAr, GluR1 and GluR2 are taken from one section, while those for GluR3 and GluR4 are taken from another. GluR1 puncta are most numerous in laminae I and II, while those that are GluR2- or GluR3-immunoreactive are present in large numbers throughout laminae I–III. The GluR4 staining was obtained with a rabbit antibody against the C-terminal part of the protein (GluR4-C antibody), and is present at relatively few puncta in laminae I and II. However some clusters of GluR4 puncta that are orientated either transversely (arrow) or dorsoventrally (arrowhead) are visible in the superficial dorsal horn. Each image was obtained from a projection of 5 optical sections at 0.3 μm z-spacing. Approximate locations of laminar boundaries are shown. Scale bar = 20 μm
