Synthesis of cyclopentadiene derivatives starting from norbornadiene was investigated using dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate. The products obtained were either cyclopentadienes or diazines depending on the substituents. The driving force for the formation of these products was discussed in terms of electronic by: Cofacial cyclopentadienes. Synthesis and reactions of 1,8-bis(cyclopentadienyl)naphthalene. Tetrahedron Letters , 30 (22), Cited by: Some of these natural compounds were previously reported to show important bioactivities, including anticancer activity, cardiovascular protection and phosphodiesterase-4 inhibition. We designed and synthesized fifteen biphenyl-containing diaryl acetylene derivatives mimicking the skeleton of Cited by: 2. Synthesis of Vicinal Diaryl Furans. A number of well-established methods for the synthesis of vicinal diaryl furans have been described in the literature. Some of the general synthetic routes to prepare vicinal diaryl furans are described below. Synthesis of Diaryl Furans by Dehydration of 1,4-Diketones.

Liebigs Annalen der Chemie , (1), Abstract: With a view to the rational design of a series of selected 42 substituted 1,3-diaryl propenone derivatives, quantitative structure-activity relationship (QSAR) models have been developed for the prediction of antimalarial activities against chloroquine-resistant strain of Plasmodium falciparum (W2). Specific advantages and disadvantages of the several synthetic methodologies are discussed. The review focuses on catalytic 2H-chromene synthesis. However, for a complete overview, synthetic routes involving some stoichiometric steps and reactions producing ring-scaffolds that are closely related to 2H-chromenes are also included.
A strategy has been established for the synthesis of 2,4‐diaryl‐1,3‐benzoxazines via a FeCl 3 ‐catalyzed annulation of ortho‐hydroxyphenyl‐substituted para‐quinone methides (p‐QMs) and imidates. This transformation proceeds under mild, operationally‐simple conditions in a very short time. A series of 2,6-diaryl-4,8-dihydroxy-3,7-dioxabicyclooctanes, including 4,8-dihydroxysesamin, a naturally occurring lignan, have been prepared via the corresponding dilactones. The 1 H and 13 C n.m.r. spectra have been compared and the bistoluene-p-sulphonate of 4,8-dihydroxyeudesmin has been reduced by lithium aluminium hydride to give (±)-eudesmin. A facile synthetic approach to photoactive diarylethenes comprising a cyclopentene ring as an ethene bridge was developed based on reduction of 2,3-diaryl(hetaryl)cyclopentenones through an ionic hydrogenation reaction. The method provides access to unsymmetrical photoswitchable diarylethenes containing benze. Synthesis of Some Vicinal Diaryl Oxadiazoles Most of the vicinal diaryl oxadiazoles have been reported to be prepared by 1,3-dipolar cycloaddition reaction (Alcaide et al., ) or Mitsunobu reaction (Tron et al., ).
