A catalytic process for the chemo- and regioselective functionalization of nonprotected carbohydrates has been developed. This novel process allows selective thiocarbonylation, acylation, and sulfonylation of a particular hydroxy group in a particular carbohydrate in the simultaneous presence of structurally similar carbohydrates such as anomers. In addition, the chemoselectivity can be switche...
An overview of the in vitro test results on several human tumour cell lines of several series of organotin compounds synthesized at the Free University of Brussels VUB. Several compounds exhibit excellent antitumour activities. in vivo screening also gave very promising results.
The reaction of Cl(3)Sn(CH(2))(2)COOCH(3), [H(2)P(2)W(12)O(48)](12-) and WO(4)(2-) in acetate buffer solution led to the hydrolysis of estertin into a carboxyethyltin group and the assembly of a new tetra(organotin)-decorated boat-like polyoxometalate.
Efficiency of ionic liquid supported organotin reagents in halodemetalation reaction has been investigated. High radiochemical yields of astatinated and iodinated compounds have been obtained using simple work-up procedure. This methodology represents a straightforward approach for the preparation of molecular imaging and therapy agents in nuclear medicine.
3-(2-furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula r3snl (r=me, et, n-bu, ph and cy) and r2snl2 (r=me and n-bu). these complexes have been characterized by elemental analyses, ir, 1h-nmr, mass and mössbaure spectroscopy.
