Phosphoryl Radicals from Trivalent Iminyl Phosphines: A Photocatalytic Approach to N‐Phosphoryl Azetidines

Angewandte Chemie, EarlyView.
Photochemically generated phosphoryl radicals from iminyl phosphines enable strain‐release addition to azabicyclobutanes, providing access to elusive N‐phosphoryl azetidines. Combined experimental, computational, and EPR studies reveal an unconventional water‐assisted photoredox pathway.

Engaging Sulfonamides: Intramolecular Cross-Electrophile Coupling Reaction of Sulfonamides with Alkyl Chlorides

, 2019
The application of amine derivatives as coupling partners is rare due to the inherent strength of the C–N bond. Herein, we report the first cross-electrophile coupling reaction of unstrained benzylic sulfonamides.

Katalysatoraktivierung als Schlüsselfaktor in Kreuzkupplungen: Raumtemperatur‐Kupplungen schwacher Nukleophile ermöglicht durch [Pd(1‐MeNAP)TFA]2 Präkatalysatoren

Angewandte Chemie, EarlyView.
Bei vielen Pd‐katalysierten Kreuzkupplungen hat sich gezeigt, dass die Katalysatorleistung durch dessen Aktivierung begrenzt wird. Methylnaphthyl (MeNAP)‐Palladiumtrifluoracetat‐Dimere werden als leicht zu lagernde und handhabende Präkatalysatoren vorgestellt, die sich unter Reaktionsbedingungen schnell aktivieren, selbst wenn nur schwach ...

Dual targeting of cancer-related human matrix metalloproteinases and carbonic anhydrases by chiral N-(biarylsulfonyl)-phosphonic acids

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
A series of nanomolar phosphonate matrix metalloproteinase (MPP) inhibitors was tested for inhibitory activity against a panel of selected human carbonic anhydrase (CA, EC 4.2.1.1) isozymes, covering the cancer-associated CA IX and XII.

A randomized, pilot trial comparing full versus escalating dose regimens for the desensitization of AIDS patients allergic to sulfonamides

Brazilian Journal of Infectious Diseases
Sulfonamides are drugs extensively used in the management of AIDS patients. However, the use of sulfonamides is often associated with the development of allergic reactions, provoking the substitution of the drug (by another that may be less effective ...
