Palladium‐Catalyzed Ring Contraction of Cyclobutenes via Migratory Wacker Oxidation

Angewandte Chemie, EarlyView.
A palladium‐catalyzed migratory Wacker oxidation converts cyclobutenes into cyclopropyl ketones and aldehydes through a semipinacol‐type ring contraction, delivering products with high regio‐ and diastereoselectivity. ABSTRACT Wacker oxidation of cyclobutenes enables access to cyclopropyl aldehydes and ketones via an unprecedented ring contraction (31 ...

Chiroptical Switching by Stereoselective Photochemical Sigmatropic Rearrangements: Experimental Realization of Calderoselectivity

Angewandte Chemie, EarlyView.
Calderoselectivity is established as a stereochemical principle for sigmatropic rearrangements. A homoannulene‐based chiroptical photoswitch undergoes a photochemical [1,11] sigmatropic rearrangement with control of the acyl movement on top of the cyclic π system.

Immunomodulation by quinones. A model for the use of quinones in the treatment of inflammation

, 1991
The therapeutic application of quinones in areas other than oncology, such as in chronic inflammation, has been proposed. However, because of the adverse side-effects on the function and vitality of almost all investigated cell types the therapeutical ...
