Die Spaltung von 1,3-Dithianen (I) zu Carbonylverbindungen (II) gelingt oxidativ mit uberschussigem Dimethylsulfoxid und Salzsaure in Dioxan in guten Ausbeuten. 
Highly Efficient, and Fast Solid State Deprotection of 1,3-Dithianes and 1,3-Dithiolanes using Mercury(II) Nitrate Trihydrate
A variety of 1,3-dithianes and 1,3-dithiolanes are deprotected in the solid state to the corresponding parent carbonyl compounds in excellent yields using mercury(II) nitrate trihydrate in a mild,
Developments in the deprotection of thioacetals
Dithioacetals are very important and commonly used protecting groups for carbonyl compounds. Among the advantages of their use are the ease of formation, stability under both acidic and basic
A Concise, Enantiospecific Total Synthesis of Chilocorine C Fueled by a Reductive Cyclization/Mannich Reaction Cascade.
It is shown that a carefully orchestrated sequence with several chemoselective transformations, including a designed cascade that accomplishes 9 distinct chemical reactions in one pot, can smoothly forge that domain and ultimately enable a 15-step, 11-pot enantiospecific synthesis of the natural product.
Scope and Applicability of an Expedient Synthesis Leading to Polysubstituted 3‐(Carboxyphenyl)pyrroles
Abstract A convenient three‐step route toward a functionalized pyrrole building block for novel anti‐inflammatory agents is reported. In contrast to previous strategies, the present approach focuses
Keto–enol tautomerism and hydration of 9-acylfluorenes
Keto-enol tautomeric constants and ionisation constants have been measured for the keto and enol tautomers of 9-formyl-, 9-acetyl- and 9-benzoyl-fluorene in aqueous solution at 25 °C. Values of
Enantioselective synthesis for the antipodes of slagenins B and C: establishment of absolute stereochemistry.
The absolute stereochemistries of naturally isolated slagenins B and C were assigned to be (9R,11R,15R)-1b and (9 R,11S,15S)-1c, respectively.
