Photochemical studies on aromatic γ,δ-epoxy ketones: efficient synthesis of benzocyclobutanones and indanones.
نویسندگان
چکیده
Irradiation of terminal aromatic γ,δ-epoxy ketones with a 450 W UV lamp led to Norrish type II cyclization/semi-pinacol rearrangement cascade reaction which formed the benzocyclobutanones containing a full-carbon quaternary center, whereas irradiation of substituted aromatic γ,δ-epoxy ketones led to the indanones through a photochemical epoxy rearrangement and 1,5-biradicals cyclization tandem reaction.

Stereocontrolled synthesis of carbocyclic compounds with a quaternary carbon atom based on SN2' alkylation of γ,δ-epoxy-α,β-unsaturated ketones.
We developed a new method for stereoselective construction of an all-carbon quaternary stereogenic center on a carbocyclic ring based on regio- and stereoselective S(N)2' alkylation reactions of γ,δ-epoxy-α,β-unsaturated cyclic ketones. Treatment of the ketones, which were readily prepared in enantiomerically pure form by means of aldol condensations between 3-ethoxy-2-cycloalkenones and α,β-ep...
متن کامل(CF3CO)2O/CF3SO3H-mediated synthesis of 1,3-diketones from carboxylic acids and aromatic ketones
A very simple and convenient reaction for 1,3-diketone preparation from carboxylic acids and aromatic ketones in TFAA/TfOH system is described. When the β-phenylpropionic acids were used as starting materials, they initially gave 1-indanones and then underwent further acylation with the formation of 2-(β-phenylpropionyl)-1-indanones as the main reaction products. In addition, the application of...
متن کاملEngineering reactions in crystals: gem-dialkoxy substitution enables the photodecarbonylation of crystalline 2-indanone
The photochemical reactivity of three 1,1,3,3-tetrasubstituted 2-indanones was investigated in solution and in crystals. While solution irradiation of tetramethyl-2-indanone 2 leads to 1-isopropenyl-2-isopropyl benzene 5 in high yield, crystals of 2 were completely inert. In contrast, samples of 1,3-bis(ethylenedioxy)-2-indanone 3 reacted efficiently in both media. While solution irradiation yi...

متن کاملIridium-catalyzed regioselective decarboxylative allylation of β-ketoacids: efficient construction of γ,δ-unsaturated ketones.
A highly regioselective protocol for the direct synthesis of γ,δ-unsaturated ketones from β-ketoacids and allylic alcohols was proposed and accomplished relying on the combination of [Ir(cod)Cl]2 and 10-camphorsulfonic acid via decarboxylative allylation.
