A convenient procedure has been developed for the synthesis of p-tert-butylthiacalix[4]arene derivatives modified at the lower rim with anthraquinone fragments linked through acetamide spacers. The products showed moderate ...

The synthesis of new phenothiazine derivatives, analogs of Methylene Blue, is of particu-lar interest in the design of new drugs, as well as in the development of a new generation of agents for photodynamic therapy. In ...

The reaction of 1,2-diaminoethane with vinylphosphonate occurs as the addition of the amino group to the β-carbon atom of the unsaturated substrate to give 1:1 and 1:2 adducts. The nucleophilic addition of 2-aminoethanol ...

© 2019, Springer Science+Business Media, Inc. An approach to p-tert-butylthiacalix[4]arene derivatives functionalized with lactic acid fragments in three conformations (cone, partial cone, 1,3-alternate) was developed. The ...

A convenient method for the synthesis of the first generation PAMAM dendrimers based on the thiacalix[4]arene has been developed for the first time. Three new PAMAM‐calix‐dendrimers with the macrocyclic core in cone, partial ...

Promising membrane transport and separation systems for selected dicarboxylic, α-hydroxy- and α-amino acids based on thiacalixarene platform have been developed. For the first time, p-tert-butyl thiacalix[4]arenes ...

© 2019, Springer Science+Business Media, Inc. The paper reports the first synthesis of positively charged hybrid organic-inorganic silicon dioxide nanoparticles with an average particle diameter of 28 nm modified with ...

Reaction of 2-acetyl-5-methyl-2H-1,2,3-diazaphosphole with ethane-1,2-dithiol at -30°C leads to the formation of 2-acetyl-3-(β- mercaptoethylthio)-5-methyl-1,2,3-diaza-phospholene. On heating, this product forms ...

Dialkyl 3-methylbuta-1,2-dienyl- and vinylphosphonates take up imidazole at the β-carbon atom in the unsaturated fragment to give the corresponding β-(1H-imidazol-1-yl)alkenyl-and alkylphosphonates. © 2007 Pleiades Publishing, ...
