for the transesterification of aryl or heteroaryl esters with phenols which is a challenging and underdeveloped transformation. The simple conditions and the use of heterogeneous alkali metal catalyst make this protocol very environmentally friendly and practical. This reaction fills in the missing part in transesterification reaction of phenols and provides an efficient approach to aryl esters, which

reaction conducted using a redox active ester with aryl zinc reagent was developed. This method demonstrates a new disconnection approach for formation of arylaryl esters. In the one-pot sequential process, the readily available aryl carboxylic acids can be converted into functionalized arylaryl esters and heteroaryl esters. This protocol is amenable to the gram-scale synthesis. The present method

Para‐substituted aromatic ethers with benzophenone or related structural elements and a 3‐(1H‐imidazol‐4‐yl)propyloxy moiety were prepared by Mitsunobu‐type ether synthesis or SNAr reaction. Most of the title compounds possess high antagonist potency in histamine H3‐receptor assays in vitro as well as in vivo in mouse CNS following oral administration. After defining 4‐(3‐(1H‐imidazol‐4‐yl)propyloxy)phenyl
