Palladium(II)-exchanged hydroxyapatite (PdHAP; Pd/Ca ratio = ca. 1/200) was prepared by ion-exchanging with Ca2+ from calcined hydroxyapatite and Pd(NO3)2 in water at 70 °C for 24 h. The PdHAP functioned as a catalyst for the Suzuki–Miyaura-type c...

Desmosine, a crosslinking amino acid of elastin, is an attractive biomarker for diagnosis of chronic obstructive pulmonary disease (COPD). In this study, the first total synthesis of (+)-desmosine was achieved in 11% overall yield in 13 steps util...
Copper(II)-exchanged hydroxyapatite, prepared by ion-exchanging of Ca(II) in calcium hydroxyapatite [Ca-10(PO4)(6)(OH)(2)] with Cu(NO3)(2) at 70 degrees C in water, functions as a reusable heterogeneous catalyst with neither reducing agents nor ba...
The E isomer of a [5]cumulene derivative, 2,2, 9,9-tetramethyl-3,8-diphenyldeca-3,4,5,6,7-pentaene (1), which was previously believed to be unisolable owing to very fast E/Z isomerization, was isolated and structurally characterized. The Z isomer ...
Ruthenium complexes bearing ethylbis(2-pyridylethyl)amine (ebpea), which has flexible -C2H4- arms between the amine and the pyridyl groups and coordinates to a metal center in facial and meridional modes, have been synthesized and characterized. T...
