Synthesis of Multisubstituted Allenes, Furans, and Pyrroles via Tandem Palladium-Catalyzed Substitution and Cycloisomerization

A palladium-catalyzed propargyl substitution reaction of propargyl acetates with indium organothiolates is developed for the synthesis of multisubstituted allenyl sulfides. This procedure can be applied to the synthesis of multisubstituted furans and pyrroles via tandem palladium-catalyzed propargyl substitution and cycloisomerization reaction in one pot.

Studies on the regio- and stereoselectivity of halohydroxylation of 1,2-allenyl sulfides or selenides

It was observed that the halohydroxylation of 1,2-allenyl sulfides or selenides with Br2 (CuBr2 or NBS) or I2 and water demonstrated a fairly good regioselectivity (i.e., the C=C bond that is remote from the S or Se atom w

o-quinone methides from 4-allenylcyclobutenones: Synthesis and chemistry

Selected 4-allenylcyclobutenones ring expand to the corresponding o-quinone methides upon thermolysis in refluxing toluene or benzene. These reactive intermediates were not isolated but trapped to give stable products. The reaction has synthetic potential as a route to highly-substituted phenols, benzofurans, and aryl analogs of hexahydrocannabinol. In addition, a unique rearrangement involving a methyl migration from silicon to carbon of selected 4-[3,3-bis(trimethylsilyl)-1,2-propadienyl]cyclobutenones to give 1,2-benzoxasilols is described. Finally, data are presented that show rapid rotation around the alkylidene bond of o-quinone methides at 30°C and that 2-(1-methylethenyl)phenols are in equilibrium with the corresponding o-quinone methides.

Chemistry of Allene Sulphoxides: Novel Transformations of Acetylenic Alcohols

The preparation and reactions of allenes derived from 1-phenylthio substituted acetylenic alcohols are described; this chemistry offers new routes to allenyl sulphides, acyl anion equivalents, and substituted unsaturated aldehydes.

Thermal and Photochemical Reactions of Organocobaloximes with Diphenyl Disulphide and Diphenyl Diselenide

Alkyl- and benzyl-bis(dimethylglyoximato)pyridinecobalt(III) complexes react with diphenyl disulphide or diphenyl diselenide, thermally and photochemically, to give good yields of alkyl or benzyl phenyl sulphides or selenides.Chiral alkylcobalt(III) complexes react to give racemic alkyl phenyl sulphides or selenides.Allyl- and propadienyl-bis(dimethylglyoxymato)pyridinecobalt(III) complexes react similarly to give the thermodynamically more stable allyl, propadienyl, or propynyl phenyl sulphides or selenides.These reactions are interpreted in terms of free radical processes in which organic radicals formed as a result of thermal, photochemical, or chemically induced homolysis of the organocobalt complex, attack the diphenyl dichalcogenide to give the product organo phenyl chalcogenide.No evidence could be obtained for the direct attack of phenylthiyl or phenylselenyl radicals on the organic ligand of the organocobalt complexes, though this process cannot be excluded in the case of allylcobalt complexes.
