The direct carbonylativepalladiumcatalyzedsynthesis of monoprotected 1,3-ketoaldehydes is reported starting from aryl iodides applying near stoichiometric amounts of carbonmonoxide. Besides representing platforms for a variety of heterocyclic structures, these motives serve as viable precursors for the highly relevant aryl methyl ketones. The presented strategy can also be adapted for the facile

rapid and programmable construction of bi‐ or multiaryls. To this end, the next frontier of synthetic modularity will likely arise from harnessing the coupling space that is orthogonal to the powerful Pd‐catalyzed coupling regime. This report details the realization of this concept and presents the fully selective arylation of aryl germanes (which are inert under Pd0/PdII catalysis) in the presence of
radicals, generated in situ. A simple metal-free borylation of aryl iodides mediated by a fluoride sp2–sp3 diboron adduct is described. The reaction conditions are compatible with various functional groups. Electroniceffects of substituents do not affect the borylation while steric hindrance does. The reaction proceeds via a radical mechanism in which pyridine serves to stabilize the boryl radicals, generated
Novel catalytic reductions of tertiary and secondaryphosphineoxides to phosphines have been developed. Using tetramethyldisiloxane (TMDS) as a mild reducing agent in the presence of copper complexes, PO bonds are selectively reduced in the presence of other reducible functional groups (FGs) such as ketones, esters, and olefins. Based on this transformation, an efficient one pot reduction/phosphination

The present invention pertains generally to the field of therapeutic compounds, and more specifically to certain amino-ethyl-amino-aryl (AEAA) compounds which, inter alia, inhibit protein kinase D (PKD) (e.g., PKD1, PKD2, PKD3). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit PKD, and in the treatment of diseases and conditions that are mediated by PKD, that are ameliorated by the inhibition of PKD, etc., including proliferative conditions such as cancer, etc.
