Tribenzotriquinacenes bearing three peripheral or bridgehead urea groups stretched into the 3-D space
نویسندگان
چکیده
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.

New 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 کاملEffects of adamantane alterations on soluble epoxide hydrolase inhibition potency, physical properties and metabolic stability.
Adamantyl groups are widely used in medicinal chemistry. However, metabolism limits their usage. Herein, we report the first systematic study of adamantyl ureas and diureas bearing substituents in bridgehead positions of adamantane and/or spacers between urea groups and adamantane group, and tested their effects on soluble epoxide hydrolase inhibitor potency and metabolic stability. Interesting...
