Metal-free formal synthesis of phenoxazine

Beilstein Journal of Organic Chemistry, 2018
A transition metal-free formal synthesis of phenoxazine is presented. The key step of the sequence is a high-yielding O-arylation of a phenol with an unsymmetrical diaryliodonium salt to provide an ortho-disubstituted diaryl ether.

Deviations from Arrhenius behavior.

, 2013
(a) Arrhenius plot relative to data in Figure 1b. Solid line indicates the linear fit of the data in the range 42–57°C. Dashed line is a guide for eyes. (b) 1/τc as a function of Con A concentration for the aggregation processes at 52 and 62°C.

Interaction of the dual targeting peptide of Thr‐tRNA synthetase with the chloroplastic receptor Toc34 inArabidopsis thaliana

FEBS Open Bio, 2015
Organellar proteins synthesized in the cytosol are usually selective for only one destination in a cell but some proteins are localized in more than one compartment, for example in both mitochondria and chloroplasts.
