Tribenzotriquinacenes bearing three peripheral or bridgehead urea groups stretched into the 3-D space
The syntheses of tribenzotriquinacenes (TBTQ) bearing three phenylurea groupings at either the arene periphery or at the benzhydrylic bridgeheads of the rigid, convex-concave, C(3) (v)-symmetrical molecular framework are reported. (1)H NMR data point to supramolecular aggregation of these TBTQ derivatives in low-polarity solvents.
متن کاملNew C(3v)-symmetrical tribenzotriquinacenes bearing extended and oxy-functionalised alkyl groups at their benzhydrylic bridgeheads.
A series of tribenzotriquinacene derivatives bearing three oxy-functionalised alkyl groups at the benzhydrylic bridgeheads (C-4b, C-8b and C-12b) have been synthesised. The 4b,8b,12b-triallyl derivative was used to generate the corresponding TBTQ-tris-acetaldehyde and TBTQ-tris(acetic acid), in which the functional groups stretch out from the convex rigid molecular surface. The corresponding tr...
متن کاملOne-pot highly efficient synthesis of substituted pyrroles and N-bridgehead pyrroles by zinc-catalyzed multicomponent reaction.
A convenient zinc(II) chloride-catalyzed regioselective propargylation/amination/cycloisomerization process has been developed for the synthesis of substituted pyrrole derivatives from propargylic acetates, enoxysilanes and primary amines. Various aromatic and aliphatic propargylic acetates participate well in the reaction, providing the propargylation/amination/cycloisomerization products in g...
متن کاملEffect of bridgehead substitution in the Grob fragmentation of norbornyl ketones: a new route to substituted halophenols.
Grob fragmentation of suitably designed bicyclic species often generates novel organic skeletons in a facile manner. Herein, we report a comprehensive account of an effective acid-catalyzed Grob fragmentation of trihalonorbornyl ketones to dihalophenol derivatives in good yields. The transformation entails tri-n-butyltin hydride (TBTH) mediated regioselective reduction of one of the two bridgeh...
متن کاملThe Type 2 Intramolecular Diels-Alder Reaction: Synthesis and Chemistry of Bridgehead Alkenes.
Anti-Bredt alkenes, bicyclic molecules that contain a bridgehead double bond, were for many years regarded as chemical curiosities. The type 2 intramolecular Diels-Alder (IMDA) reaction provides a one-step entry into this fascinating class of molecules. The reaction has made available numerous anti-Bredt alkenes for structural and chemical studies. X-ray crystallography has revealed the magnitu...
