, p. 165 - 172 (2007/10/02)
The interaction of one equivalent of NaBHT (BHT-H = butylated hydroxytoluene) with Me3SiCl, Me2SiCl2 and SiCl4 gives Me3Si(BHT) (1), Me2SiCl(BHT) (2) and Cl3Si(BHT) (3), respectively, which have been characterized by 1H NMR, IR spectroscopy and elemental
Symmetrical Alkoxysilyl Ethers. A New Class of Alcohol-Protecting Groups. Preparation of tert-Butoxydiphenylsilyl Ethers

, p. 2602 - 2608 (2007/10/02)
The preparation and evaluation of a new class of alcohol-protecting groups, the alkoxydiphenylsilyl ethers, are described.In particular, tert-butoxydiphenylsilyl ethers, which can be formed from primary, secondary, or tertiary alcohols and tert-butoxydiphenylsilyl chloride, offer the useful synthetic properties of acid stability and high fluoride reactivity.Opportunities for selective silyl group cleavage are highlighted.

5,6,7,8-Tetrahydroquinolines. Part 6. Silylation vs. Thioamidation in the Reaction of Silyl Isothiocyanates with Organometallics: Influence of the Solvent and of the Substituent on Silicon.
Crossley, Roger,Shepherd, Robin G.
, p. 1917 - 1920 (2007/10/02)
The influence of a number of variables on carbophilic vs. silicophilic attack by 8-lithio-3-methyl-5,6,7,8-tetrahydroquinoline on silyl isothiocyanates is reported.In general carbophilic attack (i.e. thiomidation) is favoured in solvents of low polarity a
Preparation of fused carbocyclic ring derivatives of pyridine
-
, (2008/06/13)
An improved process for preparing fused carbocyclic ring derivatives of pyridine especially 5,6,7,8-tetrahydroquinoline 8-nitriles, amides and thioamides is described. The nitriles and thioamides are anti-ulcer and/or anti-secretory agents. Typically a co
