FeCl3·6H2O/acetaldehyde, a versatile system for the deprotection of ketals and acetals via a transacetalization process

Mild and efficient catalytic deprotection of ketals/acetals mediated by FeCl3·6H2O/acetaldehyde has been described in this paper. The versatility and high chemoselectivity of the iron(iii)/aldehyde system are demonstrated by a large scope of examples. Deprotected ketones/aldehydes are nearly quantitatively isolated after filtration over a pad of silica gel followed by evaporation of volatile by-products.

Traceless OH-Directed Wacker Oxidation-Elimination, an Alternative to Wittig Olefination/Aldol Condensation: One-Pot Synthesis of α,β-Unsaturated and Nonconjugated Ketones from Homoallyl Alcohols

A new method for one-pot synthesis of β-substituted and β,β-disubstituted α,β-unsaturated methyl ketones from homoallyl alcohols by sequential PdCl2/CrO3-promoted Wacker process followed by an acid-mediated dehydration reaction has been developed. Remarkably, internal homoallyl alcohols delivered regioselectively nonconjugated unsaturated carbonyl compounds under the same protocol. A new starting material-based synthesis of α,β-unsaturated and nonconjugated methyl ketones is demonstrated.

Synthesis of 2,2-Diphenyl-3-oxetanol Derivatives and Their Thermal or Acid-catalyzed Decomposition

A series of five different 2,2-diphenyl-3-oxetanols was synthesized by photocycloadditiion of benzophenone and enol trimethylsilyl ethers followed by protolysis of the resultant 3-trimethylsiloxyoxetanes.Thermal cleavage and acid-catalyzed rearrangement of these oxetanes are described.

Studies on the Preparation and Reactions of Tritylsulfenimines

Carbonyl compounds react with stable, crystalline triphenylmethanesulfenamide (TrSNH2, 4) under mild conditions to form tritylsulfenimines 5 and 6.Lithiation of acetone tritylsulfenimine (5c) at O deg C led to a novel rearrangement-decomposition producing

Preparative Aspects of 1,3-Dithiolanes Synthesizable from β-Dicarbonyl Compounds

The reaction of 1,2-ethanedithiol (1) with the β-dicarbonyl compounds 2 leads to the 1,3-dithiolanes 3 which are accessible to regioselective reactions at the free carbonyl function.Thus the derivatives of the β-keto acid esters can be hydrolyzed to give the corresponding carboxylic acids 4 which make the ester group modified 1,3-dithiolanes 3 accessible in good yields.Addition of trimethyloxonium tetrafluoroborate produces the monodithiolanium salts 6 which on hydrolysis rapidly decompose into 2 and the vinyl thioethers 8.Reaction of 3 with Grignard reagents 10 yields the 2-(2-hydroxyalkyl)-1,3-dithiolanes 11.Dethioacetalization of 11 with HgO/BF3 leads to the β-hydroxy ketones 12.The retro reaction of 3 leads to the basic compounds 2 which, however, are obtained only in moderate yields. - Finally the performance of the sensitive silylenol ether 13 starting from 3g is described.
