<P>Treatment of allenyne-1,6-diols with gold and silver catalysts selectively produced 2,5-dihydrofuran and furan derivatives, respectively, in good to excellent yields through the selective activation and differentiation of the double and triple bonds in allenyne-1,6-diols. It is noteworthy that the chemoselectivity is clearly switched by simply changing the metal from gold to silver.</P> <B>Graphic Abstract</B> <P> <img src='wiley_img/16154150-2008-350-4-ADSC200700471-content.gif' alt='wiley_img/16154150-2008-350-4-ADSC200700471-content'> </P>

Regioselectivity on the reactions of α,β-enones with organoindium such as in situ generated allylindium and allenylindium was systematically studied in the presence of TMSCl as an additive. Treatment of 2-cyclohexen- 1-one, carvone, 2-cyclohepten-1-one, and chalcone with allylindium reagent produced 1,4-addition products in good yields, while 2-cyclopenten-1-one, 2-methyl-2-cyclopenten-1-one, 4,4-dimethylcyclohexen-1-one, 3- nonen-2-one, 4-hexen-3-one, and 4-phenyl-3-buten-2-one afforded 1,2-addition products. Indium reagent derived from indium and propargyl bromide in Grignard type gave addition products in good yields, under which the successive addition of α,β-enone and TMSCl were necessary. Although organoindium reagent derived from propargyl bromide produced propargylated compound in Grignard type except 2-cyclohepten-1- one, indium reagent obtained from 1-bromo-2-butyne having γ-methyl group gave allenylated product in Barbier type.

We evaluated the usefulness of PCR assays that target the internal transcribed spacer (ITS) region for identifying mycobacteria at the species level. The conservative and species-specific ITS sequences of 33 species of mycobacterial species-specific primers were designed. All PCRs were performed under the same conditions. The specificities of the primers were tested with type strains of 20 mycobacterial species from the American Type Culture Colletion; 205 clinical isolates of mycobacteria, including 118 Mycobacterium tuberculosis isolates and 87 isolates of nontuberculous mycobacteria from 10 species; and 76 clinical isolates of 28 nonmycobacterial pathogenic bacterial species. PCR with the panmycobacterial primers amplified fragments of approximately 270 to 400 bp in all mycobacteria. PCR with the M. tuberculosis complex-specific primers amplified an approximately 120-bp fragment only for the M. tuberculosis complex. Multiplex PCR with the panmycobacterial primers and the M. tuberculosis complex-specific primers amplified two fragments that were specific for all mycobacteria and the M. tuberculosis complex, respectively. PCR with M. avium complex-, M. fortuitum-, M. gordonae-, M. scrofulaceum-, and M. szulgai-specific primers amplified specific fragments only for the respective target organisms. These novel primers can be used to detect and identify mycomacteria simultaneously under the same PCR conditions. Furthemore, this protocol facilitates early and accurate diagnosis of mycobacteriosis.

Allylindium and propargylindium reagents in situ generated from the reactions of indium with allyl halides and propargyl halides could participate as nucleophiles in Pd-catalyzed substitution reactions of allyl carbonates to produce 1,5-dienes and 1,5-enynes in good yields. β-Hydride elimination products were produced in case of carbonates having β-hydrogens. Because organoindium reagents obtained from allyl or propargyl halides and indium have previously not been used to Pd-catalyzed allylic and propargylic substitution reactions, these results should provide more opportunities for the development of new C-C bond forming reactions.

BACKGROUND:: Although the use of filling agents for soft-tissue augmentation has increased worldwide, most consensus statements do not distinguish between ethnic populations. There are, however, significant differences between Caucasian and Asian faces, reflecting not only cultural disparities, but also distinctive treatment goals. Unlike aesthetic patients in the West, who usually seek to improve the signs of aging, Asian patients are younger and request a broader range of indications. METHODS:: Members of the Asia-Pacific Consensus group—comprising specialists from the fields of dermatology, plastic surgery, anatomy, and clinical epidemiology—convened to develop consensus recommendations for Asians based on their own experience using cohesive polydensified matrix, hyaluronic acid, and calcium hydroxylapatite fillers. RESULTS:: The Asian face demonstrates differences in facial structure and cosmetic ideals. Improving the forward projection of the “T zone” (i.e., forehead, nose, cheeks, and chin) forms the basis of a safe and effective panfacial approach to the Asian face. Successful augmentation may be achieved with both (1) high- and low-viscosity cohesive polydensified matrix/hyaluronic acid and (2) calcium hydroxylapatite for most indications, although some constraints apply. CONCLUSION:: The Asia-Pacific Consensus recommendations are the first developed specifically for the use of fillers in Asian populations. CLINCIAL QUESTION/LEVEL OF EVIDENCE:: Therapeutic, V.
