Green Synthesis and Urease Inhibitory Activity of Spiro-pyrimidinethiones/spiro-Pyrimidinones-barbituric Acid Derivatives
Sulfonic acid functionalized SBA-15 (SBA-Pr-SO3H) with pore size 6 nm as an efficient heterogeneous nanoporous solid acid catalyst exhibited good catalytic activity in the Biginelli-like reaction in the synthesis of spiroheterobicyclic rings with good yield and good recyclability. Spiro-pyrimidinethiones/spiro-pyrimidinones-barbituric acid derivatives were synthesized in a simple and efficient ...

متن کاملSynthesis of novel spiro-isoxazoline and spiro-isoxazolidine derivatives of tomentosin
Plants have a long history as therapeutics in the treatment of human diseases and have been a continuous source of inspiration for the development of new medicines. Among them, the genus Inula (Asteraceae) comprisesmore than 100 species, many of which are widely used in traditional medicine for a variety of biological purposes including anti-inammatory, anti-cancer and antibacterial activities...
متن کاملSynthesis and Spectroscopic Characterization of a Series of New Anthralin Derivatives and Their Corresponding Spiro-Hetherocycles
Several 10-substituted anthralins were readily prepared. Their oxidation with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone gave the corresponding novel heteroatomic systems. All derivatives were fully characterized by IR, Mass and 1HNMR spectroscopy.
