Anionic Synthesis

Abstract A new general functionalization methodology (GFM) is applied to the synthesis of trimethoxysilyl-functionalized polymers. This GFM involves (a) the preparation of a well-defined polymeric organolithium compound (PLi) using alkyllithium-initiated anionic polymerization; (b) quantitative silyl hydride-functionalization of PLi with chlorodimethylsilane to form PSi(CH3)2H; (c) hydrosilation of PSi(CH3)2H with vinyltrimethoxysilane in the presence of Karstedt's catalyst. The desired PSi(OCH3)3 was obtained in > 80% yield. The product was characterized by SEC, 1H and 13C NMR and MALDI-TOF mass spectrometry.

The One

(2S,3R,6R)-2-[(R)-1-Hydroxyallyl]-4,4-dimethoxy-6-methyltetrahydro-2H-pyran-3-ol was isolated in 18% after treating the glucose derived (5R,6S,7R)-5,6,7-tris[(triethylsilyl)oxy]nona-1,8-dien-4-one with (1S)-(+)-10-camphorsulfonic acid (CSA). The one-pot formation of the title compound involved triethylsilyl (TES) removal, alkene isomerization, intramolecular conjugate addition and ketal formation. The compound was characterized by 1H and 13C NMR spectroscopy, ESI mass spectrometry and IR spectroscopy. NMR spectroscopy was used to establish the product structure, including the conformation of its tetrahydropyran ring.
