DOUBLE bondsPRECIOUS metalsCARBONYL groupSelective hydroboration of CC single bonds presents a fundamental challenge in the chemical industry. Previously, only catalytic systems utilizing precious metals Ir and Rh, in conjunction with N‐ and P‐ ligands, could achieve this, ensuring bond cleavage and ...
4C). In addition to the covalent bond with C522, some significant interactions were proposed, such as the hydrophobic interaction from L526, the hydrogen interaction from T688, and the carbonyl-πinteraction from N660. NMS-859 induced protein dysregulation and wild type Hela cell death with an ...

Employment of acetonitrile (ACN) drastically shifted the 3/4 ratio to the CC forming bond reaction (Table 1, entry 4); however, conversion was found to be poor under the same conditions. Table 1. Photocatalytic CC coupling between 1 and 2 by DBP/DPA as TTA system.a EntrySolventConv/%b3...

lones, rubrolones, and rubterolones (Fig. 1A) are a group of unique natural glycosylated tropolonoids produced in actinomycetes, sharing similar aglycone skeletons of a cyclopentanone ring, a tropolone unit, and a deoxysugar connected from C-2' to the aglycone through a unique C-C bond....
The term “C2-Cn-alkenyl”, is used for a group as defined in the definition for “C1-Cn-alkyl” with at least two carbon atoms, if at least two of those carbon atoms of said group are bonded to each other by a double bond. The term “C2-C6-alkenyl” (including those which are...
