All target compounds and intermediates were characterised by multinuclear NMR studies (1H, 13C, 15N, 19F, 29Si) and elemental analyses or high-resolution mass spectrometry. Additionally, some of these compounds were characterized by single crystal X-ray diffraction studies.}, subject = {Silicium}, language = {en} } @phdthesis{Daiss2004, author = {Daiß, J{\"u}rgen Oliver}, title = {Synthesis of sila-analogs and silicon-containing derivatives of drugs and development and application of the Si-2,4,6-trimethoxyphenyl moiety as a novel protecting group in organosilicon chemistry}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-11187}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2004}, abstract = {The present work describes the synthesis of sila-venlafaxine, disila-bexarotene, disila-AG-045572 (disila-CMPD1), a series of silicon-based allosteric modulators of muscarinic receptors, and a partial synthesis of sila-gabapentin. Crystal structure data of rac-sila-venlafaxine hydrochloride, (R)-sila-venlafaxine hydrobromide, bexarotene, disila-bexarotene, and disila-AG-045572 (disila-CMPD1) are included. Studies on the biological activities of sila-venlafaxine and of silicon-based allosteric modulators of muscarinic receptors are discussed. The Si-2,4,6-trimethoxyphenyl (Si-2,4,6-TMOP) moiety is described as a novel, acid-labile protecting group in organosilicon chemistry. The synthesis of chlorotris(chloromethyl)silane and tris(chloromethyl)methoxysilane is described.}, subject = {Wirkstoff}, language = {en} } @phdthesis{Cota2010, author = {Cota, Smaranda}, title = {Contributions to the Chemistry of Higher-Coordinate Silicon: Synthesis, Structure, and Stereodynamics of New Penta- and Hexacoordinate Silicon(IV) Complexes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-52312}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2010}, abstract = {Im Vordergrund dieser Arbeit stand die Synthese und strukturelle Charakterisierung penta- und hexakoordinierter Silicium(IV)-Komplexe.
