- 4-Substituted indazoles as new inhibitors of neuronal nitric oxide synthase
-
A series of halo-1-H-indazoles has been synthesized and evaluated for its inhibitory activity on neuronal nitric oxide synthase. Introduction of bromine at the C4 position of the indazole ring system provided a compound almost as potent as the reference compound, that is, 7-nitroindazole (7-NI). The importance of position 4 is further demonstrated by the synthesis and pharmacological evaluation of the 4-nitroindazole which was also a potent inhibitor of NOS activity. These compounds also exhibited in vivo NOS inhibitory activity, as attested by potent antinociceptive effects following systemic administration.

- Application of C-H Functionalization in the Development of a Concise and Convergent Route to the Phosphatidylinositol-3-kinase Delta Inhibitor Nemiralisib
-
This paper describes the development of an improved and scalable method for the manufacture of nemiralisib, a phosphatidylinositol-3-kinase delta inhibitor. Incorporation of three consecutive catalytic reactions, including a palladium-catalyzed C-H functionalization and an iridium-catalyzed borylation, significantly simplified and shortened the synthetic sequence. The revised route was successfully implemented in a pilot plant on a multikilogram scale to deliver >100 kg of product.

- A practical synthesis of a PI3K inhibitor under noncryogenic conditions via functionalization of a lithium triarylmagnesiate intermediate
-
We report a practical synthesis of PI3K inhibitor GDC-0941. The synthesis was achieved using a convergent approach starting from a thienopyrimidine intermediate through a sequence of formylation and reductive amination followed by Suzuki-Miyaura cross-coupling. Metalation of the thienopyrimidine intermediate involving the intermediacy of triarylmagnesiates allowed formylation under noncryogenic conditions to produce the corresponding aldehyde. We also investigated aminoalkylation via a benzotriazolyl-piperazine substrate as an alternative to the reductive amination route. We evaluated both palladium and nickel catalyzed processes for the borylation and Suzuki-Miyaura cross-coupling. Final deprotection and salt formation afforded the API.

- New practical synthesis of indazoles via condensation of o-fluorobenzaldehydes and their O-methyloximes with hydrazine
-
The reaction of o-fluorobenzaldehydes and their O-methyloximes with hydrazine has been developed as a new practical synthesis of indazoles. Utilization of the methyloxime derivatives of benzaldehydes (in the form of the major E-isomers) in this condensation effectively eliminated a competitive Wolf-Kishner reduction to fluorotoluenes, which was observed in the direct preparations of indazoles from aldehydes. Reaction of Z-isomers of methyloximes with hydrazine resulted in the formation of 3-aminoindazoles via a benzonitrile intermediate.
