New compounds of formula 1 are provided which by virtue of their pharmaceutical activity as PI3-kinase modulators may be used in the therapeutic field for the treatment of inflammatory or allergic diseases.
Examples of these include inflammatory and allergic respiratory complaints, inflammatory diseases of the gastro-intestinal tract and motor apparatus, inflammatory and allergic skin diseases, inflammatory eye diseases, diseases of the nasal mucosa, inflammatory or allergic conditions involving autoimmune reactions or inflammations of the kidney.
A Mn‐catalyzed diastereo‐ and enantioselective hydrogenation of α‐substituted β‐ketoamides has been realized for the first time under dynamic kinetic resolution conditions. anti‐α‐Substituted β‐hydroxy amides, which are useful building blocks for the synthesis of bioactive molecules and chiral drugs, were prepared in high yields with excellent selectivity (up to >99 % dr and >99 % ee) and unprecedentedly
The first highly enantioselective α‐fluorination of 2‐acylimidazoles utilizing iridium catalysis has been accomplished. This transformation features mild conditions and a remarkably broad substrate scope, providing an efficient and highly enantioselective approach to obtain a wide range of fluorine‐containing 2‐acylimidazoles which are found in a variety of bioactive compounds and prodrugs. A large

A one-step approach to borylated cyclobutanes from amides of carboxylic acids and vinyl boronates is elaborated. The reaction proceeds via the thermal [2 + 2]-cycloaddition of in situ-generated keteniminium salts.
