The palladium-catalyzed electrochemical C-H bromination of benzamide derivatives under divided cells is developed, in which NH4Br serves as a brominating reagent and electrolyte. The protocol avoids the use of chemical oxidants and provides an alternative method for the synthesis of aryl bromides.

Synthesis, crystal structures, insecticidal activities, and structure-activity relationships of novel N ′- Tert -Butyl- N ′-substituted-benzoyl- N -[di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1, 3]([1,4])dioxine}carbohydrazide derivatives

Several series of novel N′-tert-butyl-N′-substituted-benzoyl-N- [di(octa)hydro]benzofuran{(2,3-dihydro)benzo[1,3]([1,4])dioxine}carbohydrazide derivatives Ia, Ib, IIa-IIg, IIIa, IIIb, and Va-Vc were designed and synthesized. Their structures were confirmed by 1H NMR spectra, HRMS, and X-ray single-crystal structures. The larvicidal activities against oriental armyworm, beet armyworm, diamond-back moth, and corn borer of these compounds were evaluated and contrasted with those of RH-2485, JS-118, and ANS-118. The larvicidal activities against oriental armyworm indicate that monosubstituent or multisubstituents and the substituting group position cannot promote increasing activities and that the cycle region in the general structure of IIa-IIg is much more sensitive to activity than that in the general structure of Ia and Ib. The space volume of the A ring in the structure of Va cannot be too large; if it is, the activity will be decreased significantly. Stomach toxicities against beet armyworm, diamond-back moth, and corn borer of compounds Ia, Ib and IIg indicate that benzoheterocyclic analogues of N-tert-butyl-N,N′- diacylhydrazines show significant selectivities to different lepidopterous pests.

A simple methodology for the reduction of acid chlorides to their corresponding alcohols has been developed. Various carboxylic acids were converted to alcohols in excellent yields using NaBH4-K2CO3 in a mixed solvent system of dichloromethane and water (1:1) in the presence of a phase-transfer catalyst at low temperature. The importance of the work is its simplicity, selectivity, excellent yield, and very short reaction time. This new reduction condition has proved to be an excellent chemoselective method for a range of acid chlorides in the presence of various functional groups.

New sildenafil analogues containing an ether ring fused into the phenyl moiety, 6a-d and 7a-d, were efficiently synthesized from the readily available starting materials, 1a-d and 2, in five steps. Ab initio calculations indicated that introduction of a cyclic ether to the phenyl group might enhance the co-planarity of the molecule. The torsional angles were calculated to be 2-3° for the 5-membered cyclic ether derivatives, 6a, 6c, 7a, and 7c, and 12-16° for the 6-membered ones, 6b, 6d, 7b, and 7d. On the other hand, sildenafil showed the least co-planarity with the torsional angle of 23° compared with the target compounds, 6a-d and 7a-d. in the enzyme assay, however, the in vitro PDE 5 inhibitory activity was found out to be inversely related to the degree of co-planarity. In other words, the least planar sildenafil showed the highest actiivty, and the most planar 5-membered cyclic ether derivatives were least active by 100-200-fold compared with sildenafil. Our study clearly demonstrated that the open chain 2'-alkoxy group of the phenyl ring, although less effective for inducing the co-planarity, seemed to act as a much better lipophilic requirement than the cyclic alkoxy moiety.

Novel benzamides as selective and potent gastric prokinetic agents. 1. Synthesis and structure-activity relationships of N-[(2-morpholinyl)alkyl]benzamides
Kato,Morie,Hino,Kon,Naruto,Yoshida,Karasawa,Matsumoto

With the purpose of obtaining more potent and selective gastric prokinetic agents than metoclopramide (1), a new series of N-[(2-morpholinyl)alkyl]benzamides (17-52) were synthesized and their gastric prokinetic activity was evaluated by determining effect on the gastric emptying of phenol red semisolid meal and of resin pellets solid meal in rats and mice. The morpholinyl moiety was newly designed after consideration of the side-chain structure of cisapride (2) and produced the desired activity when coupled with the 4-amino-5-chloro-2-methoxybenzoyl group of both metoclopramide and cisapride. Modification of the substituents of the benzoyl group markedly influenced the activity. In particular, 4-amino-N-[benzyl-2-morpholinyl)methyl]-5-chloro-2-methoxybenzamide (17) and the 4-(dimethylamino) and 2-ethoxy analogues (25 and 29) or 17 showed potent and selective gastric prokinetic activity along with a weak dopamine D2 receptor antagonistic activity.
