Synthesis of substituted aryl enol ethers

A facile route toward substituted aryl diarylvinyl ethers 4 is developed from CuI-mediated cross-coupling reaction of substituted phenols 2 with diarylvinyl bromides 3 in the presence of various bidentate-based ligands in DMF. Skeleton 3 is prepared by Yan's bromomethylenation of diarylketones 1 with CHBr3-TiCl4-Mg in the co-solvent of DME and CH2Cl2. The synthetic route obtains moderate yields from the one-step operation and the key structure of 4k is confirmed by X-ray crystallographic analysis. The CADD docking experiments of 4k have been included.

A search for unambiguous vinylic SRN1 reactions

In a search for unambiguous examples of the vinylic SRN1 route, vinyl bromides Ph(CH3)C=CHBr (10), Ph2C=CHBr (15), An2C=C(Br)An (18) and An2C=CBr2 (20) were treated with Me3CCOCH2- under photostimulation conditions in Me2SO, whereas substrates PhCH=CHBr (2), Ph2C=C(Br)Ph (3), 10 and 15 were similarly allowed to react with PhS- and PhCH2S-. With the strongly basic enolate ion, the prevailing reactions were elimination/addition routes, α-deprotonation followed by 1,2-Ph shift and bromide ion elimination, or halophilic steps. With 18, however, an SRN1 route was obtained. The weakly basic but reducing anion PhS- gave the SRN1 route with 2, 3 and 15. The nucleophilic character of the PhCH2S- anion instead prevailed with 15, whereas with 3 a variety of behaviours was obtained. The mechanistic interpretations were supported by the electrochemically determined redox potentials of the substrates. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.

CARBONYL-YLIDE ALS ZWISCHENSTUFEN DER PHOTOREAKTION AROMATISCHER KETONE MIT HALOGENKETENACETALEN

Photoreactions of benzophenones 1 with haloketene acetals 2 yield oxetanes 3 and tetrahydrofuran carboxylic esters 5 as major products.A mechanism with the intermediate formation of 1,4-diradicals and carbonyl ylides is discussed.

Reaction of Olefins with Malonic Acid Derivatives in the Presence of Manganese(III) Acetate

The reaction of methylmalonic acid with mono- and disubstituted olefins in the presence of manganese(III) acetate yielded 2-carboxy-2-methyl-4-butanolides in moderate to good yields.The reactions of bromomalonic acid and chloromalonic acid with a variety
