Journal ArticleDOI
TL;DR: In this article, the trialkylsilyl substituents enforce near-planar geometry around the GeGe bonds, in accordance with theoretical predefined pre-conditions.

Journal ArticleDOI
TL;DR: In this article, a chiral lanthanide shift reagent [EuIIICl2{R)-tppn]ClO4 which is structurally characterized by X-ray crystallography, resolves the enantiomer signals of α-amino acids in neutral aqueous solution and affords a good relation between the relative signal position of enantiomers and their absolute configurations.

Journal ArticleDOI
TL;DR: A novel intramolecular allylic migration from silicon to carbon was observed during the reaction of allylmethyldichlorosilane with tropolone in the presence of triethylamine to give an isomeric mix as mentioned in this paper.

19 citations


Journal ArticleDOI
TL;DR: In this article, disilalkylene bridged cyclic triacetylenes are prepared and subjected to the transition metal complex mediated reactions, and a variety of π-electron systems such as fulvene, dimethylenecyclobutene, and biallene are described.
Abstract: Disilalkylene bridged cyclic triacetylenes are prepared and subjected to the transition metal complex mediated reactions. In particular, the reaction with (methylcyclopentadienyl)tricarbonylmanganese gave a variety of π-electron systems such as fulvene, dimethylenecyclobutene, and biallene. Structures and reactions of these π-electron systems are described.

Journal ArticleDOI
TL;DR: Indolo[2,3-a]quinolizines 3 were stereoselectively synthesized by the intramolecular double Michael reaction of amide esters 2, the indole nitrogen of which was protected with a tosyl group using ButMe2SiOSO2CF3 in the presence of Et3N.
