摘要:
The present invention encompasses compounds of formula (V) wherein R1a, R1b, R2a, R2b, Z, R4, R5, R14, A, p, X, U, V and W have the meanings given in the claims and specification, their use as inhibitors of KRAS, pharmaceutical compositions and preparations containing such compounds and their use as medicaments/medical uses, especially as agents for treatment and/or prevention of oncological diseases.
Regioselective additions of pyrroles to a variety of optically active nitrones under smooth acidic conditions lead to chiral pyrrolic N-hydroxylamines in good to excellent yields. Depending on the position of the chirality on the nitrone partner, the addition products have been isolated with high diastereoselectivity levels. Reaction of glyoxylate based chiral nitrones either at the C-2 or at the C-3

Herein, we report a rapid and scalable continuous-flow photocatalytic approach for the carbamoylation of nitrones. This protocol makes use of readily available 4-amido-1,4 dihydropyridines as carbamoyl radical precursors. The scope of this transformation exhibits high compatibility with complex structures containing amino acids, peptides, and glycosides. Importantly, the developed method allows a photocatalytic
