A new series of sulfonylcycloureas derivatives have been synthesized and evaluated in vitro for their antitumor activity against four cancer cell lines (A431, Jurkat, U266, and K562). These compounds were prepared by the condensation of several sulfonamides (2a–m) with ethyl bis(2-chloroethyl)carbamate (1a). The relative cytotoxicity of these new derivatives in comparison to chlorambucil is reported

The present invention relates to tetrahydroisoquinoline derivatives according to formula (I), which are Positive Allosteric Modulators of D1 and accordingly of benefit as pharmaceutical agents for the treatment of diseases in which D1 receptors play a role.
An eco-friendly, simple, mild, chemo selective and highly efficient procedure for the acylation of primary and secondary amine function in various structurally and electronically aliphatic and aromatic compounds affording their corresponding N-Ac derivatives is developed. Mild conditions, simplicity and easier work-up are the main advantages of this method.

Simple, rapid, and clean condensation of sulfonamide and maleic anhydride derivatives: Synthesis of novel 1<i>H</i>- Pyrrole-2,5-diones under heterogeneous conditions
GRAPHICAL ABSTRACT ABSTRACT H6P2W18O62 is used as an efficient catalyst for the synthesis of novel N-substituted sulfonyl maleimides (1H-Pyrrole-2,5-diones) via the condensation of sulfonamide and maleic anhydride derivatives. The Dawson heteropolyacid was used with a catalytic amount of 2 mmol% in acetonitrile at reflux. The reuse of H6P2W18O62 as heterogeneous catalyst several times without decrease
