We report a method for gold(III)/sodium diphenylphosphinobenzene-3-sulfonate (TPPMS)-catalyzed direct amination of benzhydrols using 2-aminopyridines with poor nucleophilic character in water. Various functional groups such as electron-withdrawing ni

We demonstrated that crystal shape is related to the unit cell shape and that a molecular arrangement can be altered as desired by employing co-crystallization. We investigated the relationship between the crystal shape, unit cell parameters, and int

Water-promoted dehydrative coupling of 2-aminopyridines in heptane via a borrowing hydrogen strategy

RSC Advances. 11:23144-23150
A synthetic method for dehydrative N-benzylation promoted by water molecules in heptane using a π-benzylpalladium system has been developed. The presence of water significantly accelerates carbon–nitrogen bond formation, which is accomplished in a

We investigated the relationship between the proportion of achiral compounds that crystallize as chiral crystals and how halogen bonds affect the molecular assemblies in the crystals. In addition, ...

A method for synthesis without protecting groups of bis(indolyl)methanes by the (η3-benzyl)palladium system generated from a palladium catalyst and benzyl alcohol in water is developed. This domino protocol involves C3–H bond activation/benzylatio

Calix[3]aramide-based macrocycles 1 were successfully synthesized by a Glaser coupling reaction of two meta-calix[3]aramide moieties that have three ethynyl groups. The obtained macrocycles have stereoisomers: an enantiomeric pair and a meso form bas

Calix[3]aramide-based cylindrical macrocycles were synthesized by the one-step amide coupling reaction of a monomer containing two meta-alkylaminobenzoic acid units linked by para-phenylene bridges. The major products included a meso-form and an enan
