cleavage of a CCbond offers a straightforward method to functionalize organic skeletons. Reported herein is the oxidative CCbond cleavage of ketone for CN bondformation over a cuprous oxide catalyst with molecular oxygen as the oxidant. A wide range of ketones and amines are converted into cyclic imides with moderate to excellent yields. In‐depth studies show that both α‐CH and β‐CH bonds adjacent

reported. This reaction accommodates a variety of substrates, including simple primary amines, stericallyhindered β,β‐disubstituted amines, allylamine, benzylamines, and α‐amino esters. Reaction compatibility with various functionalities is also noted, particularly with alkenes, alkynes, halogens, esters, silyl ethers, and free hydroxyl groups. The nitriles were also synthesized via the oxidation of
Direct hydrogenation of a broad variety of cyclic imides to diols and amines using a ruthenium catalyst is reported here. We have applied this strategy toward the development of a new liquid organic hydrogen carrier systembased on the hydrogenation of bis-cyclic imide that is formed by the dehydrogenativecoupling of 1,4-butanediol and ethylenediamine using a new ruthenium catalyst.

Synthesis and evaluation of N-alkyl-S-[3-(piperidin-1-yl)propyl]isothioureas: High affinity and human/rat species-selective histamine H3 receptor antagonists
in the search for novel nonimidazolehistamineH3receptor (H3R) antagonists. Among them, four N-alkyl S-[3-(piperidin-1-yl)propyl]isothioureas 18, 19, 22, and 23 were found to exhibit potent and selective H3R antagonisticactivities against in vitro human H3R, but were inactive against in vitro human H4R. Furthermore, three alkyl homologs 18–20 showed inactivity for histamine release in in vivo rat
