Synthesis of aryl- and vinylacetylene derivatives by copper-catalyzed reaction of aryl and vinyl iodides with terminal alkynes
The coupling reaction of aryl iodides with terminal alkynes by using a catalyst system of CuI-PPh 3 in the presence of K 2 CO 3 as base gives the corresponding arylated alkynes in excellent yields.Expand
Iridium-Catalyzed Reaction of 1-Naphthols, N-(1-Naphthyl)benzenesulfonamides, and Salicylaldehyde with Internal Alkynes
1-Naphthols efficiently couple with internal alkynes via cleavage of the C–H bond at the peri-position in the presence of a catalyst system of [IrCl(cod)]2/PBut3 to selectively afford theExpand
Direct electrochemical analyses of human cytochromes b5 with a mutated heme pocket showed a good correlation between their midpoint and half wave potentials
Present study showed that simultaneous measurements of the midpoint and the half-wave potentials could be a good evaluating methodology for the analyses of static and dynamic redox properties of various hemoproteins including cytochrome b5. Expand
Ligand-Controlled Cross-Dimerization and -Trimerization of Alkynes under Nickel Catalysis
The cross-dimerization of diphenylacetylene with trimethylsilylacetylene via C¯H bond cleavage in the presence of a catalytic amount of bis(cyclooctadiene)nickel [Ni(cod) 2 ] together with aExpand
Microbial conversion of bamboo hemicellulose hydrolysate to xylitol
A hemicellulose hydrolysate containing 19 g L−1 xylose was prepared from the culm of bamboo (Phyllostachys pubescens) by hydrolysis with 3 % sulphuric acid with a liquor to solid ratio of 10 (g g−1)Expand
Effective Conversion of Three Diacetyl‐C‐(β‐D‐Glycopyranosyl) Phloroglucinols to Spiroketal Derivatives by Refluxing in Water
Refluxing of diacetylphloroglucinol C‐β‐D‐gluco‐, ‐galacto‐, and ‐allopyranosides in water for 1 d gave two kinds of spiroketal derivatives in total yields of 77%, 74%, and 64%, respectively. TheExpand
CEP250 mutations associated with mild cone-rod dystrophy and sensorineural hearing loss in a Japanese family
The data indicate that mutations of CEP250 can cause mild CRD and SNHL in Japanese patients, and high-resolution retinal imaging analysis, such as AO, will be helpful in diagnosing CEP 250-associated disease. Expand
