Nickel-catalyzed indium(I)-mediated double addition of aldehydes to 1,3-dienes.

In the presence of InI, Ni(acac)2 and PPh3, several 1,3-dienes were reacted with two molecules of aldehyde to give the corresponding 1,4- and 1,6-diols. The regioselectivity of the 1,4-/1,6-diol was efficiently regulated by the addition of water; the 1,6-diol was obtained selectively in dry THF, whereas the 1,4-diol was obtained predominantly in DMI containing a small amount of water.

Piezoluminescence at the air-water interface through dynamic molecular recognition driven by lateral pressure application.

Direct preparation of allylic indium(III) reagents from allylic alcohols via a reductive transmetalation of pi-allylnickel(II) with indium(I) iodide.

InI-mediated direct allylation of carbonyl compounds with allylic alcohols proceeded smoothly with catalytic amounts of Ni(acac)(2) and PPh(3) to give the corresponding homoallylic alcohols in high yields. Allylindium compounds were shown to be the real allylating agents in the present system. Substituted allylic alcohols gave branched homoallylic alcohols with syn-selectivity irrespective of the geometry of the starting allylic alcohols, whereas high anti-selectivity was observed when a bulky substituent is present in the allylic alcohols.

Role of the glutamic and aspartic residues in Na+-ATPase function in the ZrENA1 gene of Zygosaccharomyces rouxii.

The effect of replacement of negatively charged amino acid residues on the function of Na+ transport proteins of the salt-tolerant yeast Zygosaccharomyces rouxii was examined by heterologous expression of mutant proteins in a strain of Saccharomyces cerevisiae, RH16.6, that lacks native Na+-ATPase activity due to null mutations of ENA1, ENA2, ENA3, and ENA4. Mutants of Na+/H+ antiporter gene (ZrSOD2) and Na+-ATPase gene (ZrENA1) of Z.
