MANIFESTATION OF AZA-EFFECT IN 13C NMR SPECTRA OF ACETYLDIAZINES

Carbon magnetic resonance spectra are reported for isomeric acetyldiazines, and an analysis is made of the changes in chemical shifts of the acetyl-group and ring carbon atoms due to the aza-effect in the isomers. In the alpha-acetylazine series, special features of spectral properties have been revealed for 2-acetylpyrimidines.

Efficient use of 1,2-dihaloazine synthons in transition-metal-free preparation of diverse heterocycle-fused 1,4-oxazepines

A previously reported condensation reaction of ambiphilic 2-(1H-pyrazol-5-yl)phenols with various o-chloro-substituted nitroaromatic synthons to provide medicinally important tetracyclic pyrazolo[1,5-d][1,4]oxazepines was extended to more readily available and convenient-to-use 1,2-dihaloazines. Although 4,5-dichloropyridazin-3(2H)-ones and 2,3-dichloropyrazine are popular bis(electrophilic) partners in various SNAr-type condensations and also were efficiently used in the reaction reported herein, the facility with which various 3-bromo-2-chloropyridines underwent the same cyclization was unexpected. These reactions are presumed to occur as sequential intermolecular SNAr/Smiles rearrangement/intramolecular SNAr tandem reactions and provide a rare example of the transition-metal-free substitution of a bromine atom at the 3-position of a pyridine ring.

2,4,6-Triaminopyrimidine as a Novel Hinge Binder in a Series of PI3Kdelta Selective Inhibitors

Inhibition of phosphoinositide 3-kinase delta (PI3Kdelta) is an appealing target for several hematological malignancies and inflammatory diseases. Herein, we describe the discovery and optimization of a series of propeller shaped PI3Kdelta inhibitors comprising a novel triaminopyrimidine hinge binder. Combinations of electronic and structural strategies were employed to mitigate aldehyde oxidase mediated metabolism. This medicinal chemistry effort culminated in the identification of 52, a potent and highly selective inhibitor of PI3Kdelta that demonstrates efficacy in a rat model of arthritis.
