SiO2@Benzothiazole‐Cl@Fc as an Efficient Heterogeneous Catalyst for the Synthesis of 1,3,5‐Trisubstituted Pyrazoles by A3 Coupling

open access: yesChemistryOpen, EarlyView.
This research introduces the preparation and analysis of a newly heterogeneous catalyst developed silica nanospheres supporting a ferrocene‐containing ionic liquid (SiO2@Benzothiazole‐Cl@Fc) for the A3 coupling reaction. The catalyst facilitates the efficient synthesis of 1,3,5‐trisubstituted pyrazoles from aromatic hydrazides, aldehydes, and aromatic ...

Clinicopathological and molecular characterization of KRAS wild‐type pancreatic ductal adenocarcinomas reveals precursor lesions with oncogenic mutations and fusions in RAS pathway genes

open access: yesThe Journal of Pathology, EarlyView.
Abstract Pancreatic ductal adenocarcinomas (PDACs) with wild‐type KRAS constitute a small fraction of PDACs, and these tumors were recently shown to harbor frequent actionable oncogenic mutations and fusions. However, the clinicopathological features of KRAS wild‐type PDAC have not been well studied.
