Phosphoinositide 3-kinases (PI3Ks) are a family of enzymes that control a wide variety of cellular functions such as cell growth, proliferation, differentiation, motility, survival, and intracellular trafficking. PI3Kγplays a critical role in mediating leukocyte chemotaxis as well as mast cell degranulation, making it a potentially interesting target for autoimmune and inflammatory diseases. We previously disclosed a novel series of PI3Kγinhibitors derived from a benzothiazole core. The truncation of the benzothiazole core led to the discovery of a structurally diverse alkynyl thiazole series which displayed high PI3Kγpotency and subtype selectivity. Further medicinal chemistry optimization of the alkynyl thiazole series led to identification of compounds such as 14 and 32, highly potent, subtype selective, and CNS penetrant PI3Kγinhibitors. Compound 14 showed robust inhibition of PI3Kγmediated neutrophil migration in vivo.

A facile protocol for the electrophilic C-substitution (methylation, acylation, α-hydroxyalkylation, and carboxylation) of several 2-(N,N- dibenzylamino)alkan-1-ols via the carbamates 10 is reported. The stereochemistry of the lithiation is greatly influenced by the complexing diamine. The substrate-directed selection between the diastereotopic a-pro-R and pro-S protons in the TMEDA-assisted deprotonation is largely shifted towards pro-S-selectivity in the presence of (-)-sparteine (4). Each of both diastereomeric series is readily accessible in several cases.
